Densecharger, plastic which stays cool, and get the matching Pro-M mass airmeter custom calibrated and bench tested for the bends in the pipe. A nice little gain, and intake sound also is cool...
yeah, densecharger is about the best i think. demolet.com is the web site im pretty sure, i think they changed their name since i got mine. just stay away from the metal if you are going to buy one because they are just useless bling.
