I have the Zex nitrous kit for sale, i used it for about 1 month then decided to start a new project car. I had the 65 shot in it. went through about 3 bottles, 1 bottle squeezing and about 1 bottle just showing off my purge kit. I had 2 spray nozzles coming out right below my windshield and they went up about 8-10 feet high. :banana2: Bottle opener is still new in box, purge kit was used for about 2 weeks. I have all instructions. The bottle is still about half full. $400 plus shipping for zex kit, or $600 plus shipping for kit, purge and opener. Nothing wring with any of it.
