Nitrous Express 4500 Covert Crossbar Plate System Stage 6 50-300HP (10lb Bottle)

If you're looking to add a significant power boost to your 4150-flange carburetor setup, this Nitrous Express Covert Crossbar Plate System is designed to do just that. This system injects a precise mixture of nitrous oxide and fuel directly into your intake manifold, providing a substantial increase in horsepower. It's engineered for performance applications where a noticeable jump in power is desired, offering jetting for a wide range of power increases from 50 to 300 horsepower.

What sets this system apart is its Covert Crossbar plate technology. Unlike traditional spray bar designs, this plate uses a CNC-machined internal structure that eliminates external spray bars. This design promotes better fuel and nitrous atomization for improved cylinder distribution and avoids issues like spray bars sagging or rotating, which can disrupt airflow. The system includes the Lightning 45 bottle valve, which is known for its excellent flow characteristics and lighter weight compared to older brass valves. You'll also find integrated gauge ports on the plate for monitoring, a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines, and nickel-plated fittings for a clean and durable installation. It comes complete with a wide-open throttle switch, master arming switch, a 40 Amp relay, and the necessary harness to get you up and running.

This Stage 6 system comes with a 10lb nitrous bottle and is equipped with jetting for 50, 100, 150, 200, 250, and 300 horsepower increases, allowing you to tune the power output to your specific needs. Please note that this system is not CARB approved and cannot be shipped to California. It is also subject to California's Prop 65 warning.
