PRODUCT DESCRIPTION
Holley Hi-Ram nitrous plates take full advantage of the Holley Hi-Ram intake manifold. The Hi-Ram plenum plate bolts directly between the upper and lower intake manifold, making for a quick and easy installation.
Hi-Ram nitrous plates allow nitrous and fuel to be injected above each cylinder, from the side of the runner, providing direct port-like distribution, with no nozzles or spray bars to restrict flow. The Hi-Ram nitrous plate is made in the USA from solid billet aluminum with passages machined directly into the plate, so there are no spray bars to break or turn.
