i put mine on my01 last night except for the hoses which i was too tired to figure out so i went out to tha garage this morning and slipped those puppies on and off i went! i love the sound!!! not really any noticable power gains but i'm very satisfied! looks a lot better than that big bulky airbox sittin in my engine bay... but mine didn't come with the "duck bill" drain so i'm gonna have to figure something out cuz i got a little water in it when washing it this afternoon. i may just get a tightly-woven fabric showercap of some kind or something like that to put over the filter just in case cuz i have bad luck. if i didn't do anything about it, i'd end up being that 1 person hydrolocking in a very light rainshower...

 

Just a note on differences between earlier models and the 06+ S2ks. The air filter for the AEM v2 rubs against the front impact sensor which is mounted in the front bumper. Earlier models don't have a sensor in this location. Also, My Koyo radiator dosent fit with the V2 because the larger diameter piping in the V2 will not clear the fan mount on the Koyo. The Koyo is about 2 to 3 times thicker than the stock radiator.
