Overview
NOS Holley Hi-Ram LS Nitrous Plates
NOS Holley Hi-Ram LS nitrous plates provide a clean and easy way to install a nitrous system in your Hi-Ram intake manifold. These billet aluminum plates sandwich between the upper and lower intake, making installation simple. To keep things durable NOS machines each plate from one piece of 6061-T6 aluminum—then machines the passages directly into the plate and finishes them with an anodized coating to prevent corrosion. Designed to be run as a dry nitrous system, the plates are capable of supporting over 1,000 hp. Give your Holley Hi-Ram intake an extra kick with a NOS Hi-Ram LS nitrous plate. Order the model and finish recommended for your engine family application.
