Nitrous Express 20940-00 Holley High Ram Plenum Plate Nitrous System

The Nitrous Express 20940-00 is a premium plenum plate nitrous system engineered specifically for Holley Hi-Ram intake manifolds. This high-tech system bolts directly between the upper and lower intake manifold sections for a quick, clean installation without requiring extensive modifications.

Advanced Distribution Technology:

Unlike traditional systems, this plate injects nitrous and fuel into each cylinder from the side of the runner, delivering direct-port-like distribution without placing flow-restricting nozzles or spray bars inside the runners. The result is optimal flow characteristics and consistent power delivery across all cylinders.

Key Features:

• CNC-machined billet aluminum construction with integrated passages eliminates spray bar failure concerns
• Single-stage design with included jetting for 50 to 500 wheel horsepower applications
• Premium billet aluminum and carbon fiber Lightning solenoids for precise control
• Complete installation kit includes stainless steel braided lines, wiring harness, activation switches, and all mounting hardware
• Bolt-on installation requires no permanent modifications to intake manifold
• Direct side-runner injection provides superior fuel and nitrous distribution

What's Included:

This system comes complete with the plenum plate assembly, Lightning solenoids, all necessary stainless braided lines, electrical wiring, activation switches, jet selection for tuning, and every nut, bolt, and connector needed for installation. Note that this is a "no bottle" configuration and does not include a nitrous bottle or bottle valve.

Ideal for serious enthusiasts and racers looking to add significant power to Holley Hi-Ram-equipped engines with a professional-grade nitrous system.
