NX 17057 nitrous or fuel jet 0.057"

The NX HP 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, HP jets out flowed the competition by 35%! Thats right 35% more flow through the same orifice, how you ask? The HP 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.
