Oregon Jaybird, I sometimes run a cold air system, albeit not a Needswings duel system, and I sometimes I run a piece of green foam right behind the supercharger. Foam in winter, CAI in summer. If I had to pick one it would be the foam even though I don't get the dense air advantage. The foam seems faster. While that may be psychological because of the cool supercharger whine it produces, I really like it better and there is no chance of hydrolock when going through flooded intersections. Tighed 1 made his own DIY intake. Lets see if this link works.
