Overview
Show original supplier description
Part #: 67540-00
Assassinate the competition with the Assassin plate system. The Assassin is the most technically advanced single stage plate ever designed. The CNC machined design integrates the nitrous and fuel discharge ports into the outer perimeter. The Assassin offers a unique perimeter spray pattern that assures perfect nitrous-fuel distribution. Which in turn solves the problems commonly found on single plane manifolds, particularly small and big block Fords. This new innovation provides superior distribution and outstanding atomization. With no spray bars to sag, split, block airflow, or damage this is the Next Generation in nitrous plate technology.
