Description

These high tech nitrous plates bolt between the upper and lower intake manifold on Holley Hi-Ram manifolds for a quick and clean install. Nitrous and fuel are injected into each cylinder from the side of the runner providing direct port like distribution without having a flow restricting nozzle or spray bar in the runner. Systems come standard as a single stage with jetting for 50 to 500WHP. The 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. System comes 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. Systems ordered with a nitrous bottle include the new billet aluminum Lightning 500 bottle valve and stainless bottle brackets.
