Nitrous Express Holley Hi-Ram Plenum Plate Nitrous Systems

Nitrous Express Holley Hi-Ram Plenum Plate Systems take full advantage of the Holley Hi-Ram intake manifold. The Hi-Ram plenum plate bolts right in between the upper and lower intake manifold making the install super clean and quick. These systems inject nitrous and fuel above each cylinder from the side of the runner providing direct port-like distribution without having a flow restricting nozzle or spray bar. The Hi-Ram nitrous plate is made from billet aluminum with passages machined directly into the plate so there is no need to worry about spray bars breaking or spinning. The systems come complete with billet aluminum and carbon fiber Lightning solenoids, stainless steel braided lines, wiring, switches and every nut, bolt and connector needed to install the system. The systems ordered with a nitrous bottle include a billet aluminum Lightning 500 bottle valve and the stainless bottle brackets. Show Less
