Hey i got my cold air on today... After waiting about 10 days for it to ship from cali. I got it off e bay for like 42.95, and 18 for shipping.. its a 3" pipe/ with filter.. Sounds good, nice whistle noise at certain gas points... I feel like i have a little more zip... but its prolly just the "placebo intake noise effect" and im not goin any faster... o well I happy!
