"For the $$ it's a great deal. Installation was a little tricky, but hey it's already been done before (look at U-tube) someone has taken the time to show you how it's installed and for that I'm thankful. Looks good and once you put your foot into the pedal. the sweet sound of fresh air rushing into the motor lets you know of your success!
It's only been a week so not sure about gas mileage but for a 6 spd manual tranny, I love banging the gears and it's noticeable to the ear!" —Steven M from North Port, FL bought an Injen SP Series Cold Air Intake for a 2004 Nissan 350Z.
