Description

The Nitrous Express Covert Crossbar nitrous plate system features a CNC-machined design that eliminates traditional round spray bars, enhancing atomization and cylinder distribution. This 'Next Generation' system has no spray bars to sag, rotate, or disrupt airflow. It includes a 15lb nitrous bottle with the billet aluminum Lightning 45 bottle valve, which features two integrated gauge ports, a 5/8" siphon tube, a large 0.325" orifice, and an improved flow path with only one 45-degree turn. The Lightning 45 valve is also nearly one pound lighter than older brass valves. This comprehensive system includes a custom solenoid bracket, billet aluminum Y fittings, braided stainless solenoid to plate lines, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and a relay harness.
