Product Overview
The Holley Hi-Ram LS Plenum Plate System takes 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 installation super clean and quick.
Hi-Ram Nitrous Plate Systems inject nitrous and fuel into each cylinder from the side of the runner, providing direct, port-like distribution without a flow-restricting nozzle or spray bar. The Hi-Ram nitrous plate is made in the USA from billet aluminum with passages machined directly into the plate, so there is no need to worry about spray bars breaking or spinning.
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. Systems ordered with a nitrous bottle include the new billet aluminum Lightning 500 bottle valve and stainless bottle brackets.
