Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit (50-300HP) w/Composite Bottle

This is the Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit, designed to fit 4150 flange intake manifolds. It's a comprehensive system that can add anywhere from 50 to 300 horsepower to your engine, depending on the jetting you choose. If you're looking to significantly boost your engine's power output for racing or performance driving, this kit offers a robust solution.

What sets this kit apart is its billet crossbar design, which is CNC machined to eliminate traditional round spray bars. This advanced design helps ensure excellent fuel and nitrous atomization, leading to better cylinder distribution and more consistent power delivery. Unlike older designs, there are no spray bars to sag or disrupt airflow, making it a more refined approach to nitrous injection. The kit comes complete with a 12lb composite nitrous bottle featuring the billet aluminum Lightning 45 bottle valve. This valve is a notable improvement, weighing nearly a pound less than older brass valves and offering two integrated gauge ports, a 5/8" siphon tube, and a large .325" orifice for improved flow with fewer restrictions.

Beyond the core components, Nitrous Express includes everything you need to get started. You'll find a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines connecting the solenoid to the plate, and nickel-plated fittings for a clean look and reliable connections. It also includes a wide-open throttle switch to ensure nitrous is only activated under load, a master arming switch for safety, and a 40 Amp relay with its harness. The kit includes jetting for 50, 100, 150, 200, 250, and 300 horsepower gains, allowing you to tune the power output to your specific needs.
