Hey scotty,
I am going to buy a K&n air filter for my car, but I heard online that they can sometimes mess up the readings of the mass air flow sensor and cause some trouble codes. is that true?

how many miles have you seen vw new(04') beetle engines last before needing rebuild or swap?

yes they can if too much oil is on them.. Beetle engines can last long time if diesel, but if gasoline, generally they fall apart over 130 thousand miles

thanks for your quick reply, just bought the filter off amazon. and how do I remove the extra oil there is too much on it? thanks.
