Saw several posts discusing new TRD CAI, so here it is (sorry crappy droid pics). Dealer bolted on the new and old design so we could hear and the feel the difference. I opted for this one because it considerably quieter, and honestly I just prefer the look. And yes, its CARB legal according to the box, paper work, and dealer (not that I care I'm in GA!). Oh, and take notice to the "GM its time to change/clean your filter reset button/vacuum gauge"
