I'm going back on what I said concerning getting a enclosed CAI. I saw K&N
just released their CAI and pulled the trigger; I couldn't help myself. Of all the aftermarket suppliers, K&N has most always provided a dyno chart for their products. +12hp/+30ft-lbs! Pretty neat they included an aluminum intercooler pipe as part of the kit. Kinda makes one think if the other vendors performed dyno testing but didn't see the need to provided the intercoooler pipe.
I bought the CAI from Autoanything.com and they included a filter recharging kit for free, no shipping charges or tax.
