Anthony,

CAI's used to be the thing, over the last couple years they have gotten to be like a bad word on the late model sites like gmfullsize.com and performancetrucks.net. Supposedly on the new trucks the factory intakes flow just fine. There was a thread on one of those sites where they did dyno comparisons and there were no gains. I think that Keith Seymore or another engineer on this forum who had something to do with GMT900 said there is no room for improvement on these intakes.

With that said, I don't buy ALL of that, some but not all. I think they do give improved throttle response and also sound better (if that matters). If you do get one, don't get an oiled element (K&N) because the oil gets on your MAF. I have a GMPP oil free intake on my '08 because I wanted a CAI, got it for cheap and it doesn't cause any warranty discussions at the dealership.

I would pass on the K&N.
