How does this nitrous plate install?

This plate bolts between the upper and lower sections of a Holley Hi-Ram intake manifold. The nitrous and fuel are injected from the side of the runners, offering a clean installation without needing to drill into the manifold runners.

What makes this plate different from other nitrous systems?

Unlike systems that use spray bars inside the intake runners, this plate has passages machined directly into the billet aluminum. This design prevents issues like spray bars breaking or spinning, providing a more reliable nitrous and fuel delivery.

Can this nitrous plate be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

If you're looking to add a nitrous system to your Holley Hi-Ram intake manifold, this Nitrous Express plate is a solid option. It bolts right between the upper and lower sections of the manifold, making for a clean installation without needing to drill into your runners. This design injects nitrous and fuel directly into each cylinder's intake runner from the side.

This plate is machined from a solid piece of billet aluminum, which means the passages for the nitrous and fuel are built right into the plate itself. This construction avoids the common issue of spray bars breaking or spinning inside the intake runner, giving you a more reliable setup. It's designed to provide distribution similar to a direct port system, but with a much simpler installation.

Keep in mind this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and safety guidelines.
