Soooo... can't speak for Gen 2's... but the Airhammer design (of which I run an original not an LMI) was one of the only ones to make power on the dyno, unlike the K&N that lost it inspite of bold claims. I certainly hope that on the Gen 2 at the next intake face off event on LX the K&N actually up's their game and produces at least the same HP as a stock box! As for noise... think the AH design is one of the most aggresive sounding intakes on the market... and finally the TRUE cold air intake makes little difference other than at idle when IAT's will creep a little slower than an 'in the engine bay' intake. The second you step on it the IAT's are ambient anyway... agree with you there.
