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

Old school comfort

Old stone wash carpenter jeans. Fits great and very comfortable. Correct size and length. Will buy again. Had a pair of these several years ago and forgot how good Lee jeans fit.

They are back!
Color: Quartz Stone, Size: 38W x 32L
The quartz stone (my favorite color) has been sold out for at least two years. It was looking like this style was going away forever. I check my wish list last week and they are back! Same great quality as before.

Good buy, great fit!
Size: 12, Color: White
Very satisfied with the fit, style, and quality of these shoes. Usually scared to buy shoes online due to the sizing issues or difficulty. These were no sweat. Good delivery as well.
