Nitrous Express 4150 Covert Crossbar Plate System Stage 6 50-300HP (10lb Bottle)

Nitrous Express is known for its comprehensive nitrous oxide systems, and their Covert Crossbar Plate System is a prime example of their commitment to advanced technology. This Stage 6 system is designed for 4150 flange manifolds and offers a significant power increase, adjustable from 50 to 300 horsepower. It’s a well-built setup that aims to provide excellent fuel and nitrous distribution to your engine.

What sets this system apart is its CNC machined design, which eliminates traditional spray bars. This means no more issues with spray bars sagging, rotating, or disrupting airflow, leading to improved atomization and more even cylinder distribution. The system includes a 10lb nitrous bottle equipped with the billet aluminum Lightning 45 bottle valve, which not only looks good but also flows exceptionally well and is lighter than older brass valves. You also get a custom solenoid bracket, billet aluminum Y fittings, braided stainless steel lines from the solenoid to the plate, and nickel-plated fittings for a clean and durable installation.

For ease of use and safety, this kit comes with a wide open throttle switch and a master arming switch, along with a 40 Amp relay and harness. It includes jetting for 50, 100, 150, 200, 250, and 300 horsepower, giving you flexibility in tuning. The plate itself features two integrated gauge ports and an improved flow path with only one 45-degree turn, further enhancing performance. Please note that this system is not CARB approved and cannot be shipped to California.
