Nitrous Express Holley High Ram Plenum Nitrous Plate Conversion

If you're looking to add a serious shot of horsepower to your Holley Hi-Ram intake manifold, this Nitrous Express conversion plate is a solid option. It bolts right between the upper and lower sections of your Hi-Ram, giving you a clean and direct way to inject nitrous and fuel into each cylinder. This setup aims to mimic direct port injection by squirting the mixture into the side of each runner, which helps distribute it evenly without needing a nozzle or spray bar inside the intake tract itself.

The plate itself is machined from billet aluminum, meaning it's built tough and designed to last. Because the passages for the nitrous and fuel are machined directly into the plate, you don't have to worry about internal components like spray bars coming loose or spinning over time. This design contributes to a super clean look under the hood and a more reliable nitrous system. It's a well-built piece that integrates smoothly with your existing Holley Hi-Ram setup.

Keep in mind that this part is not CARB approved and cannot be shipped to California. For a complete nitrous system, you'll need to source the nitrous bottle, lines, and activation components separately.
