Hi all, in May I picked up a G8 GXP for my wife (birthday present) w/sunroof, auto in Magnetic Gray Metallic, all black interior. She loves the car, as do I. Right know it is all stock, but I would like to install a CAI, but I have had a bit of a bad experience on my 08 Duramax, it kept putting the truck in to reduced power mode and regenerating the DPF filter, the mfg of the intake would not admit that their intake was causing the problems 3 MAFs later I put the stock back on and have run it troble free ever since, any way I am interested in just the Yella Terra intake tube, or the roto fab complete CAI. I am not going to reprogram, I will later on put the SLP cat back ex. . I have a few questions, first has any one had any codes thrown from the CAI, and was it worth the extra$ over the Yella Terra intake tube. Also I live in western Oregon so I am concerned about water,(it seems to like to rain around here) snow getting into the Roto Fab intake. It is a bummer that GM finally make a great car only to take it away from us so soon.
