Nitrous Express 8 Cyl EFI Gasoline Nozzle Jet Pack (200-500 HP)NX 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. Warranty Installation

Husband loves it
Size: XX-Large, Color: Army Green
Gave this to my husband as a christmas gift and he really likes it. He says the outfit is really soft, it fits well, and the material seems to be of decent quality. Personally I think the color looks amazing, the material is super soft and not too thick and not too thin.
