Description

The Assassin plate system is the most technically advanced single stage plate ever designed. Its CNC machined design integrates the nitrous and fuel discharge ports into the outer perimeter, offering a unique perimeter spray pattern for perfect nitrous-fuel distribution. This solves common problems in single plane manifolds, especially in small and big block Fords, providing superior distribution and outstanding atomization. With no spray bars to sag, split, block airflow, or damage, this represents the next generation in nitrous plate technology. Plate thickness: 7/8". Conversion includes The Nitrous Assassin Plate, Stainless Braided Lines, Jetting from (50-300hp), Carb Studs, and Solenoid Bracket.
