Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit (50-300HP) w/o Bottle

If you're looking to add significant horsepower to your vehicle for racing or performance driving, a nitrous oxide injection system can be a game-changer. This Nitrous Express 4150 Billet Crossbar Stage 6 Nitrous Kit is designed to bolt onto 4150 flange intake manifolds, offering a substantial power increase. The core of this system is its advanced billet crossbar design, which replaces traditional spray bars. This CNC machined construction ensures excellent fuel and nitrous atomization, leading to more consistent cylinder distribution and a smoother power delivery compared to older designs. Because there are no spray bars to sag or rotate, airflow is less disrupted, making this a truly updated approach to crossbar nitrous plate technology.

This kit comes with everything you need to get started, except for the nitrous bottle itself. You'll find a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines running from 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, ensuring the system only activates when your engine is under load and you're ready for the boost. The included jetting allows you to tune for anywhere from 50 to 300 horsepower, giving you flexibility to match your desired performance level. The billet aluminum construction also means this plate weighs one pound less than older brass valve designs, contributing to a lighter overall setup.

This system is specifically configured for 4150 flange intake manifolds. Please note that this kit is not CARB approved and cannot be shipped to California. Always ensure you are familiar with local regulations and safe nitrous oxide installation practices before proceeding.
