4150 Assassin Plate Alcohol Pro-Power 100-500Hp without Bottle Nitrous Express NX 67545-00 - USA-NX-67545-00 - 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.
