About this part

Product Details

This Nitrous Express Dryquad Stage Billet Crossbar Plate System is designed for serious performance enthusiasts looking to add significant horsepower to their vehicle. It's a dry nitrous system, meaning it injects nitrous oxide directly into the intake manifold, relying on your vehicle's existing fuel system to provide the necessary fuel for combustion. This particular setup is engineered for a 4500 flange, commonly found on high-performance throttle bodies, and is capable of supporting power increases from 100 to 2000 horsepower, making it suitable for a wide range of demanding applications.

What sets this system apart is its billet crossbar plate design. Unlike traditional spray bar systems, this CNC-machined plate eliminates spray bars altogether. This means no risk of them sagging, rotating, or disrupting airflow into the cylinders. The result is improved atomization and more consistent distribution of the nitrous charge across all cylinders, leading to more efficient power delivery. The system also features an improved flow path with only one 45-degree turn, minimizing restriction. It comes complete with a billet aluminum Lightning 500 bottle valve, known for its great looks and excellent flow, weighing nearly a pound less than older brass valves. You also get a custom solenoid bracket, billet aluminum Y-fittings, braided stainless steel solenoid-to-plate lines, nickel-plated fittings, a wide-open throttle switch, a master arming switch, a 40 Amp relay, and the necessary relay harness, ensuring you have most of what you need to get started.

Included with this kit is a 10lb nitrous bottle. For installation, you'll need to ensure your vehicle's fuel system can support the added demand. 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.
