Nitrous Express 4150 Single Entry Billet Crossbar Nitrous Plate Kit (50-300HP) w/o Bottle

This Nitrous Express kit gives you a 10lb nitrous bottle complete with the billet aluminum Lightning 45 bottle valve. The valve itself is a step up, featuring two integrated gauge ports, a 5/8 siphon tube, a large .325 orifice, and an improved flow path that uses only one 45-degree turn. It also weighs nearly a pound less than older brass valves and looks sharp. This system is designed for 4150 flange manifolds and includes jetting for 50, 100, 150, 200, 250, and 300 horsepower increases.

What sets this system apart is the billet crossbar plate. Unlike traditional spray bars that can sag or disrupt airflow, this plate offers a consistent spray pattern without those issues. It's a truly updated approach to crossbar nitrous plate technology, making it legal for racing classes that only permit one nitrous and one fuel jet. The kit also comes with a custom solenoid bracket, high-flow 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 corresponding harness, so you have most of what you need to get started.

This kit is a solid option for those looking to add significant power to their 4150 flange intake manifold. Remember that this system is not CARB approved and cannot be shipped to California. You'll also want to check local regulations regarding nitrous oxide systems.
