so i'm getting a CAI soon and i've been doing some research and i can't figure out what i want. basically, right now its between the lingenfelter and the K&N 63 series Aircharger. the K&N claims gains of up to 13.95 horsepower whereas the lingenfelter only claims 12 but i'm trying not to take this into consideration as i know the gains of both are probably highly inaccurate under real world conditions. just by name alone, i feel like lingenfelter would be the best bet, i mean, it seems hard to go wrong with something from lingenfelter. but here is my main issue. looking at a picture of the lingefelter, it still has the same corrugations in it, just in different places, as the stock intake hose does. now, i thought the point of the CAI was to a) reduce IAT and b) to reduce any air flow restrictions the stock intake might have. looking at the K&N, its intake hose is smooth. This seems to me to be much better. Any opinions?
