Hey boys and girls,
I just bought a new 2010 z71 4x4 and was wanting to put a CAI on it and a programmer to get a little more power out of it. I was just wanting some suggestions or help on what to get and if its worth it. Any help will be appreciated.

For the CAI I was considering a K&N, but the programmer I have no idea about those...

also I know a programmer voids the warrenty but that can be cleared out before taking it to the dealership, does a intake void the warrenty?
