Air filters are similar to your nose. They remove all undesired particles from the air before it enters the engine. It enables only clean and pure air inside for better combustion and results in higher efficiency which results in smoother power delivery. Abrasive particle matter is kept out of the cylinders by the air intake filter, where it can cause mechanical damage and oil contamination.
A flat surface pleated paper filter element is used in the majority of fuel-injected vehicles. The filter is contained in a plastic container and is connected to the throttle frame through a duct. Older vehicles with carburetors or throttle body fuel injection, on the other hand, typically employ a cylindrical air filter. This is contained in a metal or plastic container with a top and has ducts for supplying cold or heated incoming air. The air filter covers the entire device.
Types of Air Filters –
Pleated paper filter elements are the finest alternative for automotive engine air cleaners since they are effective, easy to maintain, and economical. It’s a prevalent confusion that paper filters allow for insufficient airflow, restricting engine performance. In contrast, a correctly sized paper filter merely restricts flow if it becomes clogged with contaminants. The paper has a huge overall area, around 50 times the size of the air window.

The replacement for automotive air filters incorporates oil-wetted foam-like parts. Paper filter elements have taken their place in tiny engines, lawnmowers, and power tools. Foam filters, however, are still used on small engine air compressors. It provides for a very large dirt trap capacity while not restricting airflow. Foam filters are widely utilized in off-road and racing vehicles.
While its filtration efficiency is modest, oiled cotton gauze is being used in an increasing number of motorsport applications due to the high airflow it provides.
Another medium that allows for more airflow is Stainless steel mesh(JALI). Mesh counts provide varying filtering standards. The steel mesh over the turbo in high-end engines with limited space guarantees that no particles enter through the turbo.
