Got me a AEM CAI ... never had a problem. Running stage 4 - the FMIC with EcuTek all tuned up. I deffinetly notice a difference when the cooler weather comes around.... then again the IC like the cooler air... I'll be going to short ram when i get my FM..
This arguement has been done to death. My oppinion... dont waste the money do the silencer delete and a drop in K&N and spend the money on Samco IC hoses and a bigger scoop to get more air flow across the IC..
