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

If you're looking to add serious horsepower to your vehicle, this Nitrous Express Pro-Power Nitrous Plate Kit is a solid choice. Designed for 4150 flange manifolds, this system is built to inject a substantial amount of nitrous oxide, offering a power increase from 50 to 300 horsepower with the included jetting. The kit is engineered to integrate seamlessly with your engine's intake, providing a noticeable surge of power when you need it most.

What sets this kit apart is its billet crossbar design. Unlike older systems that use round spray bars, this CNC-machined plate eliminates those, meaning there are no spray bars to sag, rotate, or disrupt airflow. This results in much better atomization and more even distribution of the nitrous and fuel mixture into each cylinder. The kit also comes with the Lightning 45 bottle valve, which is made from billet aluminum and weighs about a pound less than traditional brass valves. It features two gauge ports, a 5/8 siphon tube, and a large .325 orifice for improved flow with fewer restrictions.

You'll find everything you need to get this system installed and running. It includes a 15lb nitrous bottle, a custom solenoid bracket, billet aluminum y-fittings, braided stainless steel lines connecting the solenoid to the plate, and nickel-plated fittings throughout. For activation, it comes with a wide-open throttle switch, a master arming switch, and a 40 Amp relay with its own harness. The included jetting covers a wide range of power increases, from 50 HP up to 300 HP, allowing you to tune the system to your specific needs. Please note that this system is not CARB approved and cannot be shipped to California.
