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-percent! That is right 35-percent 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.

Messaged Brian about the thought of doing coilovers and sway bars on my c6. He called me up and we talked for probably 30 min, awesome guy to work with/shop with. Definitely would recommend this company.
