The use of air filters in vehicles is vital to ensure the healthy and efficient operation of the engine. Air filters block dust, dirt and other particles in the air, preventing them from entering the engine. This ensures that your engine receives a clean and effective air-fuel mixture, thus increasing combustion efficiency. Additionally, regular maintenance of air filters maintains engine performance and fuel efficiency. An effective air filter prolongs the life of the engine by providing less friction and wear in the engine. When evaluating the performance of the engine, factors such as air filter cleanliness, filter blockage and air flow are taken into account. A dirty or clogged air filter may cause engine loss of power and increase fuel consumption. Therefore, it is important to check the air filter regularly and replace it when necessary.
