Nitrous Express 4150 Assassin Plate Stage 6 Alcohol 50-300HP (w/o Bottle)

If you're looking to significantly boost your engine's power output for racing or performance driving, the Nitrous Express 4150 Assassin Plate system is a serious contender. This system is designed to inject a potent mix of nitrous oxide and fuel directly into your engine's intake manifold, capable of adding anywhere from 50 to 300 horsepower. It's particularly well-suited for engines using a 4150-style carburetor flange, common on many performance V8s, and is built for alcohol fuel systems.

What sets the Assassin plate apart is its advanced design. Instead of traditional spray bars, it features CNC-machined ports integrated into the plate's perimeter. This unique approach creates a wider, more even spray pattern of nitrous and fuel, ensuring better distribution and atomization across all cylinders. This helps prevent common issues found with older spray bar designs, like uneven distribution, especially on single-plane manifolds. Since there are no spray bars to sag or block airflow, you get a cleaner intake charge and more consistent power delivery. This system is designed for alcohol fuel, which is often used in high-performance applications for its cooling properties and resistance to detonation.

This kit comes ready to integrate into your existing fuel and nitrous setup, but remember it does not include the nitrous bottle itself, so you'll need to source that separately. It's important to note that this system is not CARB approved and cannot be shipped to California. Proper installation and tuning are critical for safety and performance, so consult the manufacturer's instructions and consider professional installation if you're not experienced with nitrous systems.
