Nitrous Express 4150 Single Entry Crossbar Plate Pro-Power Nitrous Kit (100-500HP) w/Comp Bottle

If you're looking to add significant horsepower to your vehicle, the Nitrous Express 4150 Single Entry Crossbar Plate Pro-Power Nitrous Kit is a well-built system designed for 4150 flange intake manifolds. This kit uses an advanced CNC machined crossbar plate design that eliminates traditional round spray bars. This means better fuel and nitrous atomization, leading to more consistent cylinder distribution and improved performance. Because there are no spray bars to sag or disrupt airflow, this system represents a notable step forward in nitrous plate technology.

This comprehensive kit comes with a 15lb nitrous bottle equipped with the billet aluminum Lightning 45 bottle valve. This valve is not only visually appealing but also functional, featuring two integrated gauge ports, a 5/8 siphon tube, a large .325 orifice, and an improved flow path with only one 45-degree turn. The valve itself weighs nearly a pound less than older brass models, contributing to overall system efficiency. You'll also find a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel solenoid-to-plate lines, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and its harness. The system includes jetting for 50, 100, 150, 200, 250, and 300 horsepower increases, with the capability to reach up to 500HP with appropriate tuning and components.

This kit is designed for easy installation on 4150 flange manifolds. 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.
