thanks guys for the support, i work at hensler racing. 3.75 a lb for nitrous, tax included.
i've had a nitrous kit on my car for bout a year. NX is the way to go they have the best stuff, even though it might cost a lil more. learn and read about nitrous before you throw it on your car, it can be ur best friend or worst enemy, nitrous backfires suck ass
