I've heard the densecharger is a very good CAI, performing just as well as the other non-metal CAI's. No one has done a CAI "shoot-out", testing JLT vs WMS vs Densecharger. You really have to go off of what you think works the best. In theory, the JLT should make the most power with the stock MAF because the shape of the tube and the lack of bends. It's one big piece and i'd really like to try it out.
