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

These socks are just OK. One arrived with a hole (easily sewn up, but kind of bummed about that). I prefer the Under Armour Resistor socks - they have support built into the socks that you actually can feel, and they were same price for 6 pairs!

I have these same socks in white and gray, oh, and a couple of colors, and they are my favorite socks. They're the most comfortable, best-fitting socks I've ever ordered.

Perfect socks for all day wear
Size: Medium, Color: White
Light weight dry fit. Extremely comfortable very functional fits nice and is not too thick but not too thin. I wouldn’t say they are slip resistant but I am not going to try sliding around in them. I would buy again and choose over other brands I have tried before
