My caveat was that horsepower figure. If the OP wants to make more than 350 at the wheels, the better CAI will be of benefit.OP has a 5.3 engine. Blackbear told me that the OEM intake on my old 5.3 would flow more than the engine could overcome with any amount of tuning. I installed a CAI, and swapped back; they were right.
