Nitrous Express 67140-15 Assassin 4150 Plate System with 15lb Bottle Up to 750HP

The Nitrous Express Assassin Plate System represents the next generation in nitrous oxide injection technology for 4150-style carburetors. This complete kit includes everything needed to deliver up to 750 horsepower gains with a 15lb nitrous bottle, making it ideal for serious street and strip applications.

Advanced Perimeter Spray Design:

The Assassin plate features a revolutionary CNC-machined design that integrates nitrous and fuel discharge ports around the outer perimeter of the plate. This unique spray pattern ensures optimal nitrous-fuel distribution across the entire intake charge, eliminating the common distribution problems found on single plane manifolds, particularly with small block and big block Ford engines.

Key Features:

• CNC-machined billet aluminum construction for precision and durability
• Perimeter port design provides superior atomization and consistent distribution
• Single stage system capable of supporting up to 750 horsepower
• Includes 15lb capacity nitrous bottle with mounting hardware
• No spray bars to sag, split, block airflow, or suffer damage
• Fits between carburetor and intake manifold on 4150-style flanges
• Complete bolt-on kit with all necessary installation components

The Assassin's innovative design solves the atomization challenges that plague traditional plate systems, delivering race-proven performance with exceptional reliability. Perfect for racers who demand consistent, powerful nitrous delivery without compromising air flow or manifold compatibility.
