Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit (50-300HP) w/15lb Bottle

If you're looking to add significant power to your vehicle, the Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit is a serious option. This kit is designed for 4150 flange intake manifolds and offers a wide range of power increases, with included jetting for 50, 100, 150, 200, 250, and even 300 horsepower gains. It's a well-built system that aims to improve how the nitrous and fuel mix before entering your engine.

What sets this kit apart is its billet crossbar design. Instead of traditional round spray bars, this system uses a CNC machined plate that eliminates those bars altogether. This means no more worries about spray bars sagging, rotating, or disrupting airflow. The result is better atomization and more consistent distribution of the nitrous and fuel mixture to each cylinder, which is key for making power reliably. The kit also comes with the billet aluminum Lightning 45 bottle valve, which is lighter than older brass valves and features two gauge ports, a 5/8 siphon tube, and a large .325 orifice for improved flow. You'll also find 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 its harness included, making it a comprehensive package.

This system is designed for those who want a noticeable power boost and appreciate advanced design. Remember that this kit is not CARB approved and cannot be shipped to California. Always follow the manufacturer's instructions for installation and safe operation.
