Nitrous Express 4150 Assassin Plate Stage 6 Nitrous Kit (50-300HP) w/10lb Bottle

If you're looking to significantly boost your engine's power output for track days or competitive events, the Nitrous Express 4150 Assassin Plate Stage 6 Nitrous Kit is a serious contender. This system is designed to inject a controlled amount of nitrous oxide and fuel directly into your engine's intake manifold, creating a substantial increase in horsepower. It's engineered to work with 4150 throttle body style manifolds, offering a straightforward way to achieve dramatic performance gains.

What sets the Assassin plate apart is its advanced design. Instead of traditional spray bars, it features integrated nitrous and fuel discharge ports along the outer perimeter. This CNC-machined design creates a unique perimeter spray pattern, ensuring a more even distribution of the nitrous and fuel mixture across the intake manifold. This improved distribution is particularly beneficial for single-plane manifolds, helping to solve common issues like uneven cylinder filling, especially in Ford small and big block applications. The result is better atomization and more consistent power delivery, without the drawbacks of sagging or splitting spray bars.

This kit includes a 10lb nitrous bottle, providing a good capacity for multiple runs or extended use. The system is adjustable, allowing you to tune the horsepower increase anywhere from 50 to 300 HP, so you can tailor the power to your specific needs and engine's capabilities. While this kit offers impressive performance enhancements, please note it is not CARB approved and cannot be shipped to California. Always ensure you have the necessary supporting modifications and a solid understanding of nitrous system operation before installation.
