Nitrous Express 4150 Covert Crossbar Plate System Pro Power 100-500HP (5lb Bottle)

If you're looking to add a significant power boost to your vehicle with a 4150 flange carburetor, this Nitrous Express Covert Crossbar Plate System is a comprehensive solution. This system is designed to inject a precise mixture of nitrous oxide and fuel directly into your intake manifold, dramatically increasing horsepower for short bursts of acceleration. It's built for performance applications where a substantial power increase is desired, offering adjustable horsepower levels from 50 up to 300 HP with the included jetting.

What sets this system apart is its Covert Crossbar plate design. Unlike traditional spray bar systems, this CNC-machined plate has an improved flow path with a single 45-degree turn, eliminating the need for external spray bars. This design ensures excellent atomization and cylinder distribution, and because there are no spray bars to sag or disrupt airflow, you get a cleaner, more efficient charge into your engine. The system includes a Lightning 45 bottle valve, which is not only visually appealing with its billet aluminum construction 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, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness, making it a complete package for installation.

This Pro Power system comes with jetting for 50, 100, 150, 200, 250, and 300 horsepower increments, allowing you to tune the power output to your specific needs and engine's capabilities. It also includes a 5lb nitrous bottle to get you started. Please note that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
