go with whatever... there all about the same, but let me add another point, i had an AEM CAI fake me out intake at first, and that thing was poorly made, my local shop claimed it has the same exact dimensions as a real AEM CAI, same material and performance, but my friend, who had got the real AEM at the same time, his has no problems. his looks better, and his piping doesnt seem to be all busted up(mines seem to have little dents), and i take care of my car better than him, washing my car inside and out, driving much slower than him, avoiding potholes, and going over speed bumps so carefully, cleaning my K&N filter.... anyway, so be careful of knockoffs.. and one more thing, i noticed very little difference in performance, best things about them is that they made me seem like when i floored it, it sounded like i had some power... which i knew i didnt LOL. and when u turn on the car and turn it off, sounds pretty nice. i dont kno, but my friend who has an AEM hot air intake, doesnt sounds as nice, i dont kno y, when he turns on his car, doesnt make that "wooshing" noise. while me and my friends with CAI's, it does. anyway, btw, on some cars, i think intakes do something, like my friends 5 speed integra special edition(same motor as RS, LS), that made his car quite a bit faster, he raped me alot more after he got an AEM CAI. made 14-15 HP supposedly to the wheel according to one of the magazines(i dunno bout that, but sure did something). it gets more HP than the GSR does from AEM CAI, perhaps GSRs have better intake system to begin with, or whatever engine reason. but yes, on accords, they dont do much i guess. get AEM!!! =) all my friends love them.
