Unfortunately, modern fuel itself is not very combustible, therefore, in order to provide the engine with the necessary power, the fuel needs a "helper" - clean air in sufficient volume. All this in the Ford Focus 2 is provided by an air filter, which has its own strictly defined period of use, after which this element must be replaced.
According to the manufacturer's recommendations, the Ford Focus 2 air filter should be replaced every 20 thousand kilometers, that is, approximately 1 time in 3 years. However, it is worth noting that if the car is actively used or in some difficult conditions, then this period is better to be halved.
What air filters can be installed on the second generation Focus?
Currently, Ford Focus 2 can be found with a rectangular and cylindrical air filter. The first was installed on models released in 2004-2007.
The second - in 2007 and after it.
Step-by-step instructions for replacing the Ford Focus 2 air filter.
Restyling.
1. Open the car hood. It is worth noting here that all actions can be performed anywhere: a pit or overpass is not needed.
2. To the right of the engine, find a plastic box of the appropriate shape.
3. Unscrew the fixing bolts of the box cover and, pulling it towards you with some force, dismantle the latter.
4. Remove the old cartridge.
5. Thoroughly clean the inside of the housing from dirt, dust and other contaminants present there.
6. Install a new filter element in place of the old one. Close it with a lid, fixing the latter with the bolts removed at the initial stage.
7. Air filter replacement is complete. It remains only to close the hood and enjoy the responsive operation of the engine in motion.

1. It is necessary to disconnect the DMRV and the incoming air sensor, the photo shows how this should be done.
These filter elements are just as important to a car as they are. The flat rectangular cabin filter Ford Focus 2 is easy to find in stores. But you can't call it cheap. The cost of the filter starts from 500 to 1000 rubles. Looking for a replacement.
Air filter Ford Focus 2
Air purification in the Ford Focus 2 has been carried out with a cylindrical air filter in a restyled version since 2007
and a flat rectangular paper filter in the pre-styling version from 2004 to 2007.

The Ford designers subsequently installed the filter in this shape, since cylindrical filters have a large filter surface shape in comparison with their dimensions.
The replacement of the filter itself does not present a certain difficulty, however, it is necessary to take into account some circumstances related to the operation. After all, it is a mistake to assume that the work of the air filter is only to clean the air entering the engine. A properly working filter is also the following results:
- Increase in motor resource.
- Full power delivery.
- Ensuring the completeness of fuel combustion and bringing the exhaust back to normal.
- Fuel economy.
The value of air filtration
Filtering the air entering the internal combustion engine is essential. When passing through the filter, a large number of small inclusions are removed from the air - grains of sand, fluff, which, if they enter the cylinders, can cause certain damage to the internal surfaces of cylinder liners, compression rings, and rotating parts.
When the air filter is used for a long time, impurities accumulate, which not only leads to a deterioration in filtering capacity, but also makes it difficult for clean air to pass through. Albeit not significantly, but in this case, the engine power is somewhat lost. After all, low air permeability can affect the combustion of the fuel - air mixture, and in some modes, for example, during acceleration, a lot of air is required. Otherwise, you can consume fuel that will not work efficiently, and acceleration will turn out to be sluggish. In some cases, if the driver overtakes, such delay will already be very dangerous.
For information, it can be noted that a modern motor consumes up to 13 liters of air during the combustion of 1 liter of fuel. It is easy to calculate the possible volumes that pass through the filter in one period of its operation. Therefore, one should not be surprised when a significant deposit is found in a disassembled engine. And not always the fault is low-quality fuel, as is commonly believed. All particles that have entered the combustion chamber can degrade the fuel, and the appearance of deposits on the cylinder walls will not take long.
How often to change the air filter
The car air filter needs to be changed strictly at regular intervals. For the Ford Focus 2 air filter, this frequency is 20 thousand km or every three years. But when taking into account the replacement interval, it is necessary to take into account the conditions in which the car is operated. If the machine constantly works in a polluted metropolis or in dusty areas, then the replacement interval must be reduced. Moreover, the price of the air filter is not excessively high, and in no way affects how often to change the cabin filter.
The price of an air filter depends on the type of engine. Below is the estimated cost for Ford Focus air filters of 2 different engines:
1.4 liter gasoline engine - about 10 cu. e.
1.6 and 1.8 liter gasoline engine - from 9 to 14 cu. e.
1.8 liter diesel engine - from 7 to 12 cu. e.
2.0 gasoline engine - from 8 to 15 c.u. e.
It should be noted that when choosing on your own when to change the Ford Focus 2 air filter, for example, through an online store, you should opt for well-known companies that produce products of guaranteed quality. At the same time, when viewing catalogs, you can find a very significant difference in price. Nevertheless, there is no need for unnecessary savings, because buying the cheapest analogue for 4-5 USD. That is, you, on the contrary, cause even more damage to your engine. And such a replacement of the air filter can result in a subsequent expensive repair of the motor itself.
If we choose an air filter, then the following circumstance must be taken into account. Original Ford air filters not only cost a little more than high-quality counterparts, the average price varies around 20 USD. That is, but the waiting time for the delivery of the original spare part can be up to 3 weeks, which is not very convenient.
Using a Zero Resistance Air Filter
In the practice of car maintenance, more advanced filters have recently been used. As noted earlier, a conventional filter, as it gets dirty, can somewhat impede the passage of air flow. To avoid this effect, air filters have been developed and successfully used for cars that have less (or zero) resistance to the passage of air flow.
This group of filters includes some varieties:
The usual filter of zero resistance for installation in a regular box.
Zero resistance filters installed separately.
Cold air intake filter not from under the hood (remote).
The peculiarity of the zero resistance filter is that it is made of a higher quality material than a conventional filter. The main material is cotton, which does not change its properties under any conditions, including if it is wet or dirty. Contaminants are not absorbed into the material, but remain on the surface. Therefore, one of the features of using a zero resistance filter is that it needs periodic flushing and lubrication.

In the intake manifold
After passing through the filter, there is more air. Accordingly, the amount of fuel supplied also increases, which ultimately makes it possible to burn the fuel efficiently, and the engine power also grows. As measurements show, we can expect an increase in power by 5%, and at the same time, without forcing the motor, or without resorting to installing a turbine that pumps air.
American filter - nulevik K&N from China.
Zero resistance filter price slightly higher than the regular filter. Depending on the car engine, it ranges from 55 to 60 cu. e. At the same time, the service life for which the filter is designed is very large. We can say that one filter will be enough for the entire service life. Some filter companies offer a 1.5 million mile warranty. Depending on the operating conditions, periodic flushing is required after a run of 50-150 thousand km.
One of the most significant companies on the market is Green filter, which has patented technological solutions in the field of zero resistance filters.
Among other products, including those for use in the Ford Focus 2, there are filters that are not installed in a regular housing. Thus, the air that is pumped through the filter has even greater performance, and the efficiency of the motor output increases.
Among the new products from the category of zero resistance filters, one can name another variety - remote filters. The peculiarity of such a filter is to install it in a special housing, which is outside the engine compartment. This gives certain advantages, since the air is taken not only cold from the external environment, but the contamination of the air itself with oil vapor is also reduced. And the air supply is provided due to natural pressure.

Air filter selection
It has already been mentioned more than once how large the number of air filters of traditional design, which differ not only in price range, but also in quality. So, when choosing a filter element, pay attention to the following points:
- The filter element used. As a rule, special cardboard or non-woven material is used in filters. Keep in mind that the degree of purification with such materials is very high - up to 99.5%, and the filtration of cheap fakes can be 70-80%, and at the same time deteriorate quickly.
- The quality of the filter element. The main indicators for the air filter are density, strength, elasticity. Even if you do not have the ability to visually control the filter material, you can use the results of the examinations that are periodically carried out by automotive experts and specialized centers. In the future, try to be consistent without changing the manufacturer and purchase a new filter from a trusted seller.
- The diameter of the air filter seat and the geometric dimensions of the installation housing. This data can be used by you in case of selecting a filter different from the previously installed sample. Some companies offer filters with different body lengths for the same seat size, as well as with different capacities. Also a possible option is the selection by car model, year of manufacture, type of motor, which every driver should know.
One of possible ways air purification
If we consider which air filter is better for ford focus 2, then another way to purify the air should be called.
In the practice of mechanical engineering, there are known cases of using “wet” air purification filters, when air is pumped through a layer of engine oil, which is in the formed volume. Of course, cleaning in this case is quite thin, but the disadvantage of such a filter is low performance. Modern forced motors operate at high speeds, and a large amount of air is required. Older cars, for example, some models of Volga cars used such filters. Ease of use also lies in the collapsible reusable design, which, however, requires an oil change. In addition, when planning the installation of a wet filter, it is difficult to take into account how such a replacement can affect the operation of the entire engine. Therefore, in the choice of installation - oil (wet), air filter
paper (dry air filter), we must proceed from the position that we cannot harm the motor.

Of the possible varieties of wet-type filters, there is such a variety when an air flow passes through a continuously vibrating mesh. By changing direction, the flow is directed towards the oil bath, where air pollutants are deposited. This method, however, is relevant for powerful motors in agricultural machinery, where air pollution can be significant, as well as for industrial motors on ships and railway locomotives.
What's the output?
Thus, it was difficult to imagine that the simple operation of choosing a cleaning method and, in the event of a filter replacement, is associated with such numerous factors. Here is the power of the motor, and the correct clean operation of the engine, the durability of the unit itself. This is all connected with the material costs of maintaining your car, and here, as it turns out, there are no trifles.
.As you know, the Ford Focus 2 air filter serves to filter and purify the air flow from external contaminants and exhaust gases entering the car engine. Therefore, its replacement is a priority during car maintenance or when the filter fails. Today you will learn about what kind of air filter is needed in a Focus 2 car, and what types of it are, as well as how to change the cleaning element.

What filter is needed?
filter element housing
One of several types of filters can be installed in a Ford Focus 2 car, depending on the version of the vehicle, so its choice depends solely on the car.
In particular, the standard air purification element for Ford Focus 2 in a rectangular case is a traditional filter that is installed on most cars. Its cost is not cheap: 500 - 1000 rubles (150-300 hryvnias), but it is publicly available and is sold in any automotive store.
The new filter element of the restyled Ford Focus 2
As for the restyled version of the "second" Focuses, in them air purification is carried out by a cylindrical element. Such cleaning components have been installed on auto production since 2007. In the period from 2004 to 2007, pre-styling cars were equipped with a flat paper filter in a rectangular case.
Subsequently, the manufacturing company decided to install cleaners in their vehicles in this case and in this form. Cylindrical elements were found to be more inconvenient due to their overly large filtering surface and considerable size.
Below is the average cost of the air component depending on the type of engine:
- 1.4-liter engine - 600 rubles (200 hryvnias);
- 1.6l and 1.8l engines - from 500 to 900 rubles (150 - 250 hryvnias);
- diesel engine with a volume of 1.8 liters - from 350 to 700 rubles (100 - 200 hryvnias);
- 2L engine - from 400 to 1000 rubles (120 - 270 hryvnias).
One way or another, but it is better to change the element to the original one. The manufacturer recommends that owners of restyled Ford Focus 2 cars change the air filter element every 20 thousand kilometers. But the resource of the working element is significantly reduced if the vehicle is operated on roads with high dust content. Therefore, the air filter further - VF) it is better to change every 10-15 thousand km.
Replacement process
The very replacement of the cleaning air component in the restyled Ford Focus 2 is not a laborious task, so even the most inexperienced driver can handle it. The main thing is to follow the provided instructions and accurately perform all the actions.
With the timely replacement of the cleaning element, you will get the following results:
- engine life is increased;
- the power of the vehicle increases while driving;
- normal operation of the exhaust system;
- saving gasoline.
Tools
The manufacturer recommends replacing the air component together with the crankcase cleaner. Therefore, we will consider the process together with the change of this part. Before proceeding with the direct replacement, prepare everything you may need:
- wrench or wrench-head with an extension to "7";
- the air filter itself (the brand of the original element is Mahle LX 1780);
- rags;
- new crankcase gas filter;
- liquid VD-40;
- Phillips screwdriver.
Self-replacement of the element
- First you need to open the hood and find the air cleaning component housing cover.
- Then 4 bolts should be unscrewed to dismantle this cover.
- We take a key-head with an extension to "7" and unscrew this bolt. You can try to do this with a regular key, but the head will be much more convenient.
- Now you need to unscrew the two fixing bolts of the air duct and move the branch pipe. This is done for greater convenience, so that the pipe does not interfere with the removal of the old and the installation of a new filter element.
- We will immediately change the component for cleaning and ventilation of crankcase gases. You just need to pry it off with a screwdriver and pull it out, installing a new one in its place.
- Next, pull the cover up and remove it. It can be installed firmly, so it will take little effort to dismantle it.
- This is what the VF looks like after 15 thousand kilometers. You, as the driver of the vehicle, must make a visual assessment of the item's condition. In the event that, with a run of 15 thousand km, the element looks deplorable, then the replacement interval must be reduced. Then you yourself will know how often you need to change the WF.
- Now you need to dismantle the cleaning component and wipe its body from settled dust.
- We take a new VF and install it in the connector. Before that, take VD-40 fluid and lubricate the inner ring of the filter. In order for the back to fit clearly into the guides, it will need to be compressed a little.
- Now you can put the cover back in place and tighten the bolts back. Don't forget to check that the back of the element fits properly into the body.
- Screw the pipe into place.
Important! Do not think that you can save money by blowing the filter with a compressor. It is advisable to purge the element if the vehicle is temporarily used in difficult conditions and the component itself has not yet exhausted its resource.
little trick: at the installation site, mark with a marker or on a piece of paper the date and mileage when the VF changed.

Every fan of the American auto industry will surely need information about the difference between a car air filter Ford Focus 1, 2 and 3. Therefore, we decided to collect the features of these parts in one article, we will also talk about the proper maintenance of this node.
Purpose of the air filter
Absolutely every person, even one who is far from technology and not very well versed in the structure of a car, knows that the engine runs on a fuel-air mixture, and the last component should be somewhat larger. Therefore, if we take the average values, then for every hundred kilometers, about fifteen cubic meters of air passes through the engine. But there is so much dust, sand and other small particles in it, and if you ignore the cleaning process, then all these impurities will enter the motor and hit its elements, which contributes to the abrasive wear of the unit.
All this means that the air filter is an incredibly important element in the car. This part is located in a special case, and it should be noted that its location also affects the resource of the engine. Since if it is too close to the road surface, then there is a possibility of water getting in, especially when overcoming puddles after rain, which will negatively affect the performance of the motor. The correct location will not only provide a protective function, but also reduce noise, thereby increasing the level of comfort. In addition, a properly functioning air filter is the key to good power output, increased engine life, maximum fuel combustion and, accordingly, its economy.
This element is available in various shapes, most often it is a rectangle or a cylinder. The latter option has a large filtering surface area in relation to its dimensions. However, they are classified not only depending on the form, they may have a different installation scheme. The most popular are more advanced air filters on Ford Focus 2 and other generations of this car model. Their advantages include excellent performance in any conditions, it is only necessary to lubricate the element in time.
Such devices are called. Their design is thought out so that their operation does not reduce the power of the motor, even when, over time, with the deterioration of the quality of the membranes, a decrease in air flow occurs.
Features of the operation of filters on the Ford Focus
Well, the significance of the node described above cannot be underestimated in any case, therefore, each car owner is obliged to monitor its serviceability. In the case when the filter is on your Ford Focus clogged or unusable for any other reason, it should be immediately replaced with a new one. Indeed, in such a situation, the engine simply will not be able to get the required amount of air. Consequently, the combustible mixture, which should consist of certain proportions of both fuel and air, will lack the second component, which will lead to its enrichment. As a result, the fuel will not burn completely, which means that its consumption will increase significantly, while the power will decrease.
In this case, the features of the operation of the car must also be taken into account. If your Ford Focus forced to constantly travel through heavily dusty areas, it would be better to perform this operation once every one and a half years and, accordingly, after 30 thousand mileage.
How to choose air filters for Ford Focus?
Now you should consider how to choose the right air filters for Ford Focus 3, 2 and 1. So, today there is a huge variety of places where you can buy this part. These are, of course, classic auto parts stores, relatively new online markets, and specialized stations. But in any case, you should make purchases only at trusted points, so as not to fall for a cheap Chinese fake, which stands out as a branded quality product. Also note that service personnel must understand the brands and modifications of the car.
You can choose an original air filter for Ford Focus according to the following parameters: year of manufacture and equipment of the car or specialVIN-the code. Of course, in this case, you will have to pay a little more, but the excellent quality of the goods is worth it. But if, nevertheless, you decide to purchase an analogue, then you must definitely pay attention to a number of other features, including the material of the filter element. It is better to give preference to non-woven, as they have a greater degree of protection. Of course, we do not forget about the quality, it must be distinguished by good strength and reliability. And the third parameter is the size, because the air filter should fit perfectly into the body of your model. Ford Focus.
Replacing the air filter on a Ford Focus
So, this procedure does not cause any particular difficulties and will be possible even for novice motorists who do not have experience in solving such problems. First of all, you should open the hood of the car, where you will immediately find the attachment point for this spare part, the plastic case is located on the driver's side near the battery. The next step is to release access to the filter element itself. Ford Focus, for this purpose it is necessary to unscrew the bolts located around the perimeter of the cover. As you can see, all you need is a Phillips screwdriver.
