Nitrous Express 4150 Assassin Plate System Pro Power Alcohol 100-500HP (12lb 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 precise mixture of nitrous oxide and fuel directly into your engine's intake manifold, dramatically increasing horsepower. It's particularly well-suited for applications using a 4150-style carburetor and is engineered to work with alcohol-based fuels.

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

This Pro Power Alcohol version is capable of adding between 100 and 500 horsepower, giving you a wide range of tuning options. It comes with a 12-pound nitrous bottle, which is a standard size for many performance applications. Keep in mind that this system is not CARB approved and cannot be shipped to California. For optimal performance and safety, it's crucial to follow the manufacturer's installation and tuning guidelines carefully.
