Overview

This NOS plate is designed to bolt between the upper and lower intake manifold on Holley Hi-Ram LT Gen-V manifolds. This sandwich-style plate gives you an easy way to add nitrous oxide to your Hi-Ram equipped LT engine. The plate is machined from billet 6061-T6 aluminum, laser etched with NOS logo, then anodized for great looks and excellent corrosion protection. The one-piece plate features machined passages that precisely spray into the center of each cylinder runner. Plate includes jetting for up to 250 horsepower but is capable of supporting 1000+ horsepower. 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.
