Just installed the K&N CAI on my O4 and just wanted to tell everyone it Rocks !! I have not had a tune yet but very much notice increased power and the motor seems to spin up faster. I have 5K miles now and love this thing !!
What can I expect from a tune and what do they actually do? Anyone know?
Steve :cheers
