Why change your air filter?
Engine protection and top performance.
Soot, particulate matter, pollen and much more can get into your engine intake air while driving.
These dirt particles can lead to piston scoring in the combustion chamber and thus to premature wear on your engine. Electronic components like sensors located between the intake and the combustion chamber can be damaged or even destroyed from a lack of filtration.
Air filters protect against such dangers making a regular filter change an absolute must.
