The Nitrous Express 4150 Assassin plate Stage 6 kit (50–300 HP) includes a 15 lb bottle and uses a CNC-machined perimeter discharge pattern that integrates nitrous and fuel ports into the plate perimeter. That perimeter spray pattern aims to provide superior distribution and atomization on single-plane manifolds while eliminating spray-bar sag, split or airflow blockage for more consistent cylinder-to-cylinder delivery.
