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

Nitrous Express is well-known for its performance nitrous oxide systems, and their Dominator Billet Crossbar Stage 6 Nitrous Kit is a prime example of their advanced technology. This kit is designed to fit Dominator flange manifolds and offers a significant power increase, with included jetting for 50, 100, 150, 200, 250, and 300 horsepower levels. It’s a comprehensive package for anyone looking to add serious power to their vehicle.

What sets this kit apart is its billet crossbar plate, which is CNC machined to eliminate traditional round spray bars. This design ensures excellent atomization and uniform distribution of fuel and nitrous into each cylinder. Because there are no spray bars to sag, rotate, or disrupt airflow, you get a cleaner intake charge and more consistent performance. The kit also includes a 15lb nitrous bottle equipped with the billet aluminum Lightning 45 bottle valve. This valve is designed for improved flow with a single 45-degree turn, features two integrated gauge ports, a 5/8 siphon tube, and a large .325 orifice. It’s also about a pound lighter than older brass valves, contributing to a more streamlined setup.

Beyond the core components, this Stage 6 kit comes with everything you need to get started, including 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 the necessary relay harness. This thorough inclusion of components means you're getting a complete system ready for installation, designed for maximum performance and reliability.
