Nitrous Express 4 Cyl SX2 Nozzle Nitrous Kit Jet Pack (100-300HP x 2)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. Installation Instructions

Versatile and warm
Size: One Size, Color: Grey Melange
The product was great in multiple settings, like hiking in a wintry mix in Michigan or walking down the cold, windy streets of Chicago. It’s better than my previous beanie, as the cashmere had more give than the more rigid one I had before, while retaining all the warmth
