i dunno, but i got my $ on the h22,
my claim was based on the fact that i had dyno tuned my R w/ the AEM cai and then swapped it for the comptehc icebox, the ice box did make more hp/tq than the cai
and a friend's R after he took of the AEM cai and put it back to stock, the car made 1 less hp but 3 ft-lb tq MORE
so thats MY claim
im not saying AEM is ALL hype, its just that its MOSTLY hype
you dont need to spend 200+ dollars for an intake
btw the comptech icebox+ intake/filter kit cost 340 shipped, so im not biased as well,
i bought it cause i liked the way it looked and no more worrying about water
