NX Holly Hi Ram Plate Kit



Fits Holley Hi Ram


The Holley Hi-Ram 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 install a super clean and quick.

Hi-Ram Nitrous Plate 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 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 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.
