About this part

Product Details

This is the Nitrous Express Dry Single Entry Billet Crossbar Plate System, designed to add between 100 and 500 horsepower to your vehicle. It features a CNC-machined billet aluminum plate that fits a 4500 series carburetor flange, providing a clean single-entry point for nitrous oxide. Unlike older designs with round spray bars, this plate uses a crossbar design that atomizes the nitrous and fuel mixture more effectively for better cylinder distribution, and without spray bars that can sag or disrupt airflow.

This kit comes with everything you need to get started, including a 12lb carbon fiber bottle with the Lightning 500 bottle valve, which is lighter and flows better than older brass valves. You also get a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel lines from the solenoid to the plate, nickel-plated fittings, a wide-open throttle switch to activate the system only when you're accelerating hard, a master arming switch, a 40 Amp relay, and the necessary relay harness. The plate itself has two integrated gauge ports for monitoring, a 5/8" siphon tube, and a large .500 orifice with an improved flow path that minimizes turns.

Because this system is a dry kit, it relies on your vehicle's existing fuel system to supply the necessary fuel for combustion. This means you'll need to ensure your fuel system can handle the increased demand. Please note that this system is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and safety guidelines.
