Nitrous Express 66042-15 Dual Stage Billet Crossbar Plate System with Bottle - 4150 15lb

The Nitrous Express 66042-15 represents the next generation in nitrous plate technology with its precision CNC-machined billet crossbar design. This dual-stage system eliminates traditional round spray bars, delivering superior atomization and even cylinder-to-cylinder distribution while maintaining unobstructed airflow through your 4150 flange intake manifold.

Complete System Includes:

• CNC-machined billet aluminum crossbar plate for 4150 flange manifolds
• 15lb capacity nitrous bottle with billet aluminum Lightning 45 valve
• Dual-stage capability: 50-300hp and 100-500hp power ranges
• Custom solenoid mounting bracket and billet aluminum Y-fittings
• Braided stainless steel solenoid-to-plate feed lines
• Nickel-plated brass fittings throughout
• Complete jetting for 50, 100, 150, 200, 250, and 300 horsepower
• Wide-open throttle activation switch and master arming switch
• 40-amp relay with wiring harness

Lightning 45 Bottle Valve Features:

• Billet aluminum construction saves nearly one pound versus traditional brass valves
