Nitrous Express innovative plate systems bolts between the upper and lower intake manifold on Holley Hi-Ram intake manifolds for easy installations. Nitrous Express's nitrous plate is manufactured from billet aluminum and introduces fuel and nitrous from the side of the intake runner for distribution similar to direct port. By directly machining passages into the plate, the need for placing spray bars or nozzles in the runner is eliminated, resulting in no flow restrictions.
