Re: aFe Stage 2 Intake owners
CAI are not as great as what they claim, as I had an AFE stage II and removed it after a year. When I put the stocker back on, it was a surprise as the 5.7 actually runs notably better with the stock intake, and is so much quieter. The intake racket with the AFE is not a pleasant sound either, just very loud, which gets old. Low and mid range torque is lost with the AFE versus stock, and if there are any gains in HP, it's only seen at high RPM. I did direct comparisons, (new filters for both, also resetting the ECU) and the stock intake was the clear winner. IF all you do is 1/4 mile runs, the AFE might win the drag race, but for street use, the stocker wins.
