Guys, I am looking to upgrade my air filter to either a K&N induction kit or replacement panel filter. I have heard many stories of the oil from the air filter, getting into the mesh on the Mass Air Flow sensor and stopping it from working correctly. Is this a myth or has it actually happened to anyone here? Also, what are your opinions on the comparison between Induction kits and repalcement filters... Do they really differ in power increase or is it just the engine tone which changes? Cheers Dave.
