Product details
The new NX Billet Crossbar nitrous plate systems have just raised the bar in nitrous plate technology. The CNC machined design eliminates round spray bars resulting in excellent atomization and cylinder distribution. With no spray bars to sag, rotate or disrupt airflow, this is truly the Next Generation in cross bar nitrous plate technology. This system includes a 12lb composite nitrous bottle with the billet aluminum Lightning 45 bottle valve. This valve not only looks great; It is packed with features including two integrated gauge ports, 5/8 siphon tube, a large .325 orifice and an improved flow path with only one 45 degree turn. The Lightning 45 bottle valve looks great, flows great and weighs nearly one full pound less than our old style brass valve. This crossbar nitrous system includes more than the standard crossbar nitrous kit. It includes a custom solenoid bracket, billet aluminum y fittings, braided stainless solenoid to plate lines, nickel plated fittings, wide open throttle switch, master arming switch, 40 Amp relay and relay harness. This system is designed for 4150 flange manifolds and includes jetting for 50, 100, 150, 200, 250 & 300HP.
