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

If you're looking to add significant horsepower to your vehicle for track days or spirited driving, a well-designed nitrous oxide system can make a big difference. The Nitrous Express Dominator Single Entry Billet Crossbar Stage 6 Nitrous Kit is built to deliver that extra boost, offering a substantial power increase from 50 to 300 horsepower, depending on the jetting you choose.

This kit stands out with its CNC machined billet aluminum crossbar plate. Unlike older designs that use round spray bars, this crossbar design eliminates potential issues like sagging or airflow disruption, leading to more consistent fuel and nitrous atomization across all cylinders. This means you get a smoother power delivery and better overall performance. The kit comes complete with a 15lb nitrous bottle featuring the billet aluminum Lightning 45 bottle valve. This valve is not only visually appealing but also functional, with two integrated gauge ports, a 5/8 siphon tube, a large .325 orifice for high flow, and an improved flow path that minimizes restriction. It's also lighter than traditional brass valves.

Beyond the core components, Nitrous Express includes everything you need to get started. You'll 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 installation. The kit also includes a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary harness. It's designed to fit 4150 flange intake manifolds and comes with jetting for 50, 100, 150, 200, 250, and 300 horsepower gains.
