Nitrous Express GM LS 78mm 3-Bolt Nitrous Plate Kit Jet Pack 50-400 HPNX 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

Great polos at a great price
Color: Blue/White, Size: Large
Pleasantly surprised at the quality of these shirts. A bit heavier of a fabric then I anticipated but will be perfect for spring and fall. The size (large) was in fact large. :)

Great color, nice material, I’m usually buy xl but this shirt in 2xl fit terrific. It’s not loose either but just snug enough to look good
