Up until owning this car I've replaced the standard air filter with a K&N filter panel or K&N 57i induction kit. While owning my last Beemer I've come to learn that the oil they use to aid filtering can actually cause damage to the MAF. True? or maybe caused by over oiling?
I'm going to be replacing air filter soon and i'm not keen on killing my MAF so looking to try another induction kit or air filter.
Can anyone recommend a good replacement panel or is the OEM worth sticking to? Or if going down the route of replacing the whole air box has anyone got any advice on a good product or ones to avoid? Not looking to spend mega money on this either.
