Nitrous Express 4150 Billet Crossbar Pro-Power Nitrous Kit (100-500HP) w/15lb Bottle

Nitrous Express is known for making advanced nitrous oxide systems that help racers and performance enthusiasts get more out of their engines. This 4150 Billet Crossbar Pro-Power Nitrous Kit is a prime example, designed to integrate seamlessly with 4150 flange intake manifolds to boost your engine's power. It's built to deliver significant horsepower gains, with included jetting for 50, 100, 150, 200, 250, and 300 horsepower increases, and is capable of up to 500HP with proper tuning and supporting modifications.

What sets this kit apart is its CNC machined billet crossbar design. Unlike traditional systems with round spray bars, this billet crossbar eliminates those components. This means better atomization of the nitrous and fuel mixture, leading to more even distribution across your cylinders. Because there are no spray bars to sag, rotate, or get in the way of airflow, you get a cleaner, more efficient charge into your engine. The kit also comes with the billet aluminum Lightning 45 bottle valve, which is lighter than older brass valves and features two integrated 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, and a 40 Amp relay with its harness, making this a comprehensive package for adding serious power.

This kit is designed for those looking to significantly increase their engine's output. Remember that adding this much power requires supporting modifications to your engine and drivetrain, so consult with a performance specialist to ensure your vehicle is ready for the added stress. This system is not CARB approved and cannot be shipped to California.
