Add Part #NX933D to this system to make it a dual stage system. This system includes the latest technology and the best components available. 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 on 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.
