Nitrous Express 4150 Single Entry Billet Crossbar Gasoline (RNC) 250-750 HP 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

I am always on the lookout for a professional, but very comfortable shoe (education field with a lot of walking). These Florsheims fit the bill and make me wonder why I never bought these before. Something about them just didn't "look" comfortable to me but man was I wrong. These are easily among my most comfortable work shoes with the bonus of also looking more professional. I will say they have some heft to them, so if that's a problem for you these may not be right for you. As for me, they are right as rain. I purchased the black and brown ones (with white souls) and they are at the top of my rotation now. I look forward to trying some more from Thai company.
