About this part

Product Details

The Nitrous Express 4500 Assassin Plate Stage 6 Nitrous Kit is a sophisticated system designed to significantly increase your engine's power output, offering a range from 50 to 300 horsepower. This kit is built around a CNC-machined plate that integrates the nitrous and fuel discharge ports directly into its perimeter. This unique design creates a spray pattern that ensures perfect nitrous and fuel distribution, addressing common issues found with traditional spray bars, especially on single-plane manifolds for Ford small and big block engines.

Unlike systems that use spray bars, the Assassin plate eliminates the potential for sagging, splitting, or blockage, which can disrupt airflow and affect performance. The result is superior distribution and outstanding atomization of the fuel and nitrous mixture, leading to more consistent and powerful combustion. This makes it a next-generation solution for those looking to add significant, reliable horsepower to their vehicle.

This kit does not include a nitrous bottle, allowing you to select one that best suits your needs or use one you already have. Please note that this system is not CARB approved and cannot be shipped to California. It is also subject to Prop 65 warnings.
