NX Lightning solenoids feature an improved flow path that eliminates sharp turns and expansion areas in the nitrous flow path. This keeps the nitrous in dense liquid form which makes more power utilizing less nitrous. Lightning nitrous solenoids feature an integrated purge port, which allows you to connect a purge valve directly to the body of the nitrous solenoid for clean looks and less plumbing. Lightning Series solenoids feature CNC aluminum bodies topped with Carbon Fiber cans for the ultimate in weight savings. Systems with a bottle include the billet aluminum Lightning 500 bottle valve. This valve not only looks great; It is packed with features including two integrated gauge ports, a 5/8 siphon tube, a large .500 orifice, and an improved flow path with only one 45-degree turn. The Lightning bottle valve looks great, flows great, and weighs nearly one full pound less than our old-style brass valve.
