Nitrous Express GM EFI Dual Stage 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. Warranty Certificate of Origin

Good price and high quality!
This isolator relay is robust and has a higher amp load rating than the original relay. It was easy to install.
