The Nitrous Express 4500 Assassin Plate Pro Power (100–500HP) with a 15 lb bottle adapts the Assassin perimeter-port plate concept to 4500-style intakes. CNC machining places discharge ports around the plate perimeter to improve atomization and distribution on single-plane manifolds. With the included 15 lb bottle, the kit provides a larger-capacity plate-based nitrous option for controlled power bursts.
