Just thought id let you know that i have just replaced my air filter for a K&N panel filter for my C4S, had them before on other cars, but on my porsche you can defo notice the difference, just runs smoother and does seem to pick up more.

Is that a 997?
Ive got 997 2s and thought about this but not sure it makes a whole lot of difference.
Also may cancel warranty?...

Ive had alot of porsches in with k&n filters and the air mass sensors have been knackered think this is due to the oils that the filter is cleaned with...it coats the air mass sensor film and then cant give true reading.

I have just had a GT2 tested with it on a rolling road....3bhp more ?? hardley worth the money in my opinion.

3bhp on a 575bhp conversion no going to feel that are you.

I would have thought 3bhp was well within the run to run variation in any case.
