I fitted a K&N induction kit a while ago to my 2.0 mk4 and have a little question to ask:
when the car first starts up and is running cold the engine sounds like its ticking, not really the the sound I was hoping for. Its okay when its been running for a while, it sounds nice then, and when the revs are up but this ticking noise is begining to piss me off a little . Has anyone else come across this? and is there anything I can do about it without totally replacing (skint you see)?
