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

Nitrous Express is well-known for making powerful 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 of their commitment to advanced technology. It's designed for 4150 flange intake manifolds and aims to improve how nitrous and fuel are delivered to your cylinders.

What sets this kit apart is its CNC machined billet crossbar design. Instead of traditional spray bars, this system uses a solid billet piece that's machined to distribute the nitrous and fuel mixture evenly. This approach helps prevent issues like spray bars sagging, rotating, or disrupting airflow, leading to better atomization and more consistent cylinder-to-cylinder distribution. This advanced design is a step up from older crossbar systems. The kit comes with a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines connecting the solenoids to the plate, and nickel-plated fittings for a clean and durable setup. It also includes a wide-open throttle switch, a master arming switch, and a 40 Amp relay with its harness, so you have the essential components to integrate the system safely. Jetting is included for 50, 100, 150, 200, 250, and 300 horsepower increases, giving you flexibility to tune your power output. The billet aluminum valve weighs one pound less than older brass valve designs.

This kit does not include a nitrous bottle, so you'll need to source that separately. It's important to note that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and tuning to ensure optimal performance and safety.
