Fix: P5 bucking in first with the A/C on
 

K&N filter.

Yeah... I didn't believe it either. Marc (mp5) gave me his K&N since he doesn't need it anymore (doesn't fit will with his AEM intake :D). I put it in the other morning and I think it definitely makes a difference. Now I'm not saying that I suddenly got another 5 hp or anything like that, but I can tell the car is breathing a lot better. In general, the engine sounds and feels *that* much smoother with the K&N. The butt dyno says it's a good thing, and my car no longer bucks or bogs down when in first gear with the AC on.

Thanks Marc.
