I just purchased 2 Spiral Max inserts for my Injen intake. I put them in yesterday and didn't notice much of a difference at first. I reset the computer and instantly noticed a difference when I took it out again. More power and torque. I even got pulled over by a concord cop. Guess I was having to much fun. I don't know about the gas mileage yet though.
I'll tell you this though. There is no more hesitation in the high RPM range.
Does anyone else have this product?
