Nitrous Express 4150 Dual Stage Billet Crossbar Nitrous Kit (50-300 & 100-500HP) w/o Bottle

If you're looking to add significant power to your vehicle, this Nitrous Express 4150 Dual Stage Billet Crossbar Nitrous Kit is a well-built option designed for 4150 flange intake manifolds. This system uses a CNC-machined billet crossbar design, which is an updated approach that eliminates traditional spray bars. This means no more issues with spray bars sagging, rotating, or disrupting airflow, leading to improved fuel and nitrous atomization for better cylinder distribution and more consistent power delivery.

This kit is designed for dual-stage operation, offering flexibility in power output. It comes with jetting for both 50, 100, 150, 200, 250, and 300 horsepower increments for the first stage, and 100, 200, 300, 400, and 500 horsepower increments for the second stage, allowing you to tune your power boost precisely. The system includes 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. It's important to note that this kit does not include a nitrous bottle, so you'll need to source that separately.

The billet construction not only looks sharp but also contributes to a solid build. This system weighs one pound less than older brass valve designs. Remember that this system is not CARB approved and cannot be shipped to California. Proper installation and tuning are crucial for optimal performance and safety when using nitrous oxide injection.
