Nitrous Express GM EFI Dual Nozzle Jet PackNX Jets are manufactured on CNC equipment, and are guaranteed to be within . 0005 of specified jet size. In recent testing, using the same jet size, NX jets out flowed the competition by 35%! That's right 35% more flow through the same orifice, how you ask? The NX jet was designed to be more than just a hole in a piece of brass; its contoured inlet and multi stepped outlet allow turbulence free flow with no restrictions. Certificate of Origin Warranty

Nice unit
Using this for deterring my hot rod being stolen. Good price for this. Installation was no surprises and just let them try to steal my hot rod now. First one that was ordered arrived damaged, went through the process of getting a replacement which was simple and received the replacement in a couple of days.
