About this part

Product Details

If you're looking to add a significant power boost to your vehicle, this Nitrous Express Covert Crossbar Plate System is designed to do just that. This system is built for 4150 flange manifolds and offers a range of horsepower increases from 50 to 300 HP, making it a versatile option for performance tuning. The advanced CNC machined design eliminates traditional spray bars, which can sag or rotate, leading to improved fuel and nitrous atomization and better distribution to each cylinder. This means you get a more consistent and effective power delivery when you engage the system.

This Stage 6 kit comes with everything you need to get started, including a 5lb nitrous bottle equipped with the billet aluminum Lightning 45 bottle valve. This valve not only looks sharp but also offers improved flow and weighs less than older brass designs. You'll also 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 and durable setup. For safety and control, the system includes a wide-open throttle switch, a master arming switch, and a 40 Amp relay with its own harness. The included jetting allows you to tune for 50, 100, 150, 200, 250, or 300 horsepower gains.

This system is a comprehensive package for those serious about performance. 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.
