NOS sandwich-style plate systems are designed to bolt between the upper and lower intake sections on Holley Hi-Ram LS manifolds. Our dry nitrous systems give you everything you need including 2 NOS Pro-Race nitrous solenoids, brackets, hoses, jetting, and hardware, along with your choice of nitrous bottle. At the center of this system is our machined billet 6061-T6 aluminum plate laser engraved with NOS logo, then anodized for great looks and excellent corrosion protection. Our 1-piece plate features machined passages that precisely spray into the center of each cylinder. 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.
