Air filter:

It is the cheapest and easiest to do. The logic of the event is to enable the engine to get fresh air more easily. Normal, standard air filters are made of a papery substance and are located in a box attached to the engine unit. This box draws air from the front of the car through a pipe, and this air passes through the paper filter into the cylinders, into the combustion chamber.

The resistance applied during the passage of air through the filter directly affects the air entering the engine. For this, performance type air filters have been produced. In addition to holding dirty air like paper filters, these filters make the engine breathe easier because they pass air through paper filters more easily. These filters are also of three types.



1 In-Box Filter: These types of filters are removed from normal paper air filters and placed in their old places. They are the same type and size as paper filters.

2 Open Filter: This filter is connected to the air inlet of the engine by removing the box that we just mentioned and the pipe that allows it to breathe. Thus, resistance is reduced and air suction is easier.

3 Bolt-On Open Filter: This filter type is considered as the version of the direct filter applied to injection cars for carburetor vehicles. But unlike them, the air is mounted not just on the end of the suction pipe, but directly above the throttle.

Points to consider in practice:

There is a point to be considered in open filter applications. This is that the air entering the engine should not be hot. If no air intake support is provided to the open air filter, the filter will absorb the heated air under the hood, which will degrade engine performance.

The best performer of such applications is to cut the bonnet directly, if a hole is opened on the bonnet, like the Subaru Impreza, with the air filter in the mouth, it will be able to provide a significant improvement in performance by taking the air filter comfortably through this hole. If you do not want to, either for the open filter, you will direct clean, cool air to the open filter through a sufficiently large pipe somewhere in front of the car, or use an in-box filter. However, in-box filters do not have as much contribution as an open filter, which is well applied in terms of performance. In addition, open filters produce a louder and sportier sound than in-box filters.

Advantages, disadvantages

Let's say this when the subject is opened, the only drawback of performance type filters is that they make a lot of noise. If you are a sporty-hearted person, you will like this sound a lot, but it can be a bit challenging on long roads or when your dad gets on the car.

The advantages of the open filter do not end with counting. They increase performance, reduce fuel consumption, increase engine torque at every revolution. Yes, a good open filter application increases engine power by about 5%, besides, it provides a fuel consumption of around 0.5lt at 100km and also makes the engine more powerful at low revs than before.
