The oil in the KN filter gets blown downstream where it can gunk up the mass air flow sensor. Also, they breather better because they are 95% efficient at removing dirt from the air. Stock is 99% efficient. Which means the KN filter lets FOUR TIMES the ammount of dirt into your engine.
Hows about painting the plastic cylinder head cover red? Or maybe the calipers? |
