A well-planned nitrous system is like a knuckle sandwich when it comes to delivering power and the NOS Dry Nitrous Plate for Holley Hi-Ram intake manifolds makes things easier when adding nitrous to your Hi-Ram equipped engine.

Installing between the upper and lower halves of the Holley Hi-Ram intake manifold, this one-piece plate is machined from 6061-T6 aluminum, and is available in ether a clear or black anodized finish to match your particular Hi-Ram, ensuring that it will look great for a long time.

The plate features a machined passage feeding eight openings per intake runner, designed to spray precisely into the center of each cylinder. As the passages are machined directly into the plate, there’s no need to worry about spray bars breaking or coming out of alignment. The plate comes equipped with jetting for up to 250 horsepower in 50 horsepower increments, and is capable of supporting 1000+ horsepower, using separately-purchased jets.

The NOS Dry Nitrous Plate for Holley Hi-Ram intake manifolds are available in clear or black anodized finishes and include the gasket, hardware, jet holders and jetting, again, for up to 250 horsepower.
