What kind of power increase can I expect from this kit?

This Nitrous Express Assassin Plate system is designed to add between 50 and 300 horsepower to your engine. The exact increase will depend on the specific jetting used and the engine's overall tune.

How does the perimeter spray pattern improve performance?

The perimeter spray pattern integrates the nitrous and fuel discharge ports into the outer edge of the plate. This design promotes a more even distribution of the nitrous and fuel mixture across the intake manifold, leading to better atomization and more consistent power delivery compared to traditional spray bars.

Is this kit street legal in all states?

No, this system is not CARB approved and cannot be shipped to California. It is important to check your local emissions regulations regarding the use of nitrous oxide systems.

About this part

Product Details

If you're looking to add significant horsepower to your vehicle, the Nitrous Express 4500 Assassin Plate Stage 6 Nitrous Kit is a well-built option. This kit is designed to integrate seamlessly with single plane manifolds, addressing common distribution issues found on many small and big block Ford engines. It offers a substantial power increase, rated from 50 to 300 horsepower, giving you a noticeable boost when you need it.

What sets this plate system apart is its advanced CNC machined design. Instead of traditional spray bars, the nitrous and fuel discharge ports are integrated into the outer perimeter of the plate. This creates a unique perimeter spray pattern that ensures a more even and perfect distribution of the nitrous and fuel mixture. This improved distribution leads to better atomization and more consistent power delivery, helping to avoid the problems associated with sagging or splitting spray bars that can disrupt airflow. This is truly the next generation of nitrous plate technology, built for performance and reliability.

This kit comes complete with a 5lb nitrous bottle, ready for installation. 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.
