Nitrous Express 20963-00 Direct Port Dry Holley High Ram Plate Nitrous System

The Nitrous Express 20963-00 is a direct port dry nitrous plate system engineered specifically for Holley Hi-Ram intake manifolds. This high-tech nitrous plate bolts between the upper and lower sections of the Hi-Ram manifold, providing a clean and straightforward installation while delivering direct port-style distribution to each cylinder.

Key Features:

• Dry system design relies on your engine's fuel injection system to add fuel, injecting only nitrous oxide
• Direct port distribution injects nitrous into each cylinder individually from the side of the runner
• Billet aluminum construction with passages machined directly into the plate eliminates spray bars that can break or spin
• Includes Lightning Series high-flow solenoids for reliable nitrous delivery
• Single-stage system with adjustable jetting for a wide horsepower range (typically 50-500 HP)
• Complete kit includes stainless steel braided lines, wiring harness, master arming switch, wide-open throttle (WOT) switch, and all necessary hardware
• No bottle included - allows you to select your preferred bottle size separately

This system provides the performance benefits of direct port nitrous injection without the flow restriction of traditional nozzles or spray bars in the intake runners. Designed and manufactured in the USA by Nitrous Express, this kit includes every component needed for installation except the nitrous bottle.
