Im thinking of up grading the panel type air filter in my 182 to a K&N, etc. Does any one know if the fitment is the same as the Mk II 172, or do I need a 182 specific filter (which I probably cant get yet). I know an induction kit is the way to go, but I dont want to do that while its still under warranty. Anyone recommend a good panel filter, and what BHP increase can I expect?
