Product details
The Nitrous Express LS 102mm Plate System features a billet plate that fits all FAST 102 intakes. This 102mm plate bolts between the throttle body and intake making installation quick, easy and attractive. The system comes as a single stage system and includes jetting for 50, 100, 150, 200, 250, 300, 350 and 400 horsepower. The plate is pre-machined with a second set of nitrous and fuel passages so you can easily upgrade to a dual stage system by adding part # NX933D. This system includes ProPower Lightning series solenoids, 6AN feedline, braided stainless solenoid to plate lines, stainless bottle brackets, master arming switch, WOT switch as well as every nut, bolt and electrical connector needed to complete the installation. 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 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.
