Air Filters

Air filter is an important part of a car’s intake system, because it is through the air filter that the engine “breathes.” An engine needs an exact mixture of fuel and air in order to run, and all of the air enters the system first through the air filter. The air filter’s purpose is to filter out dirt and other foreign particles in the air, preventing them from entering the system and possibly damaging the engine.


Fuel filters

A car’s fuel filter is located along the fuel lines, either in the engine compartment or underneath the car by the fuel tank. It is the responsibility of the fuel filter to trap large particles in the fuel in order to prevent them from getting into the engine. Because of the tremendous force behind the up-and-down motion of the engine’s pistons, which compress the air-fuel mixture so that it will burn more efficiently, any large particles in the fuel could potentially cause serious damage to the engine. Large particles in the fuel also have the ability to clog fuel injectors, depriving a cylinder of precious fuel and requiring that the injector be cleaned or replaced. Therefore, maintaining a clean fuel filter is imperative to the performance of a cars engine.

Oil Filters


A car’s oil filter is located on the side of the engine block, which is the lower, larger part of the engine. An oil pump circulates the oil through the engine; every time the engine oil circulates, it passes through the oil filter. The oil filter protects the engine by catching any large particles in the oil, which might damage the engine if allowed to circulate freely.
