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

Another must buy on my list! Color, size and length were all good. I was a bit surprised as to the thickness of the vest, not heavy, but well made. Definitely value for money!
