About this part

Product Details

If you're looking to add significant horsepower to your vehicle for drag racing or track days, a well-designed nitrous oxide system can make a big difference. The Nitrous Express 4500 Covert Crossbar Plate System is built for serious performance, offering a clean and effective way to inject nitrous and fuel directly into your intake manifold. This system is designed to work with 4150 flange manifolds, providing a direct path for the nitrous and fuel mixture to enter your engine.

What sets this system apart is its CNC machined design, which eliminates traditional spray bars. Instead, it uses an improved flow path with a single 45-degree turn, leading to better atomization and more even distribution to each cylinder. This means you get more consistent power delivery and less chance of issues caused by sagging or misaligned spray bars. The system comes complete with a 15lb nitrous bottle featuring the billet aluminum Lightning 45 bottle valve, which not only looks great but also offers improved flow and a lighter weight compared to older brass valves. You'll also find integrated gauge ports on the valve for monitoring pressure.

This Pro Power kit is designed for a wide range of horsepower gains, from 100 to 500 HP, and includes jetting for 50, 100, 150, 200, 250, and 300 HP applications, allowing you to tune it to your specific needs. Beyond the plate and bottle, Nitrous Express includes a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines from the solenoid to the plate, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness. This comprehensive package ensures you have most of what you need to get the system installed and running, making it a solid option for those looking to significantly boost their engine's power output.
