AIR FILTER FOR FORD FIESTA/IV/Mk/Van COURIER PUMA MAZDA 323/ASTINA FAMILIA 1.3L BOSCH 1 457 433 605

The engine air filter acts as a consumable element that prevents dust, soot, small particles with air from entering the engine combustion chamber.

The filter element cleans the incoming air from harmful impurities, protects the motor from clogging. For complete combustion of fuel in an internal combustion engine, it is necessary that the air content in the combustible mixture is up to 20 times greater than that of fuel. Outside the car, the air contains dust particles, seeds of various plants, and so on, if these components get to the engine, they will begin to act as abrasive elements and accelerate engine wear.
