from their website:
"Injen's innovative filter design equals more HP!
In 1999 Injen set out to develop the ultimate filter design. After extensively testing rubber and plastic compounds we came upon a urethane rubber that is able to withstand elevated temperatures with zero distortion. Urethane is a light weight material which will not fade and will hold its shape for the life of the filter. We pioneered the technique of incorporating the built-in velocity stack in the filter base. Injen Technology filters have been tested repeatedly on a flow bench and on a dynomometer against the leading competition's filter elements and have out-performed them every time. ( See our web-site for test results.) Based on these test results it's no wonder that the competition has taken steps to duplicate our filter design utilizing our techniques in molding urethane compounds. "
Just a note, but they show about 13-14 hp gain with their CAI.. I talked to one of the guys over their and they do MANY runs on the dyno, and post the average gain on their website.
edit-I changed the HP.. I was reading Tq #'s
