The Nitrous Express 20940-15 is a high-performance plenum plate nitrous system specifically engineered for Holley Hi-Ram intake manifolds. This system installs cleanly between the upper and lower intake manifold sections, delivering nitrous and fuel directly into each cylinder from the side of the runner for superior distribution without flow-restricting spray bars or nozzles.

• Direct port-style distribution delivers even fuel and nitrous to each cylinder
• Single stage system with jetting for 50 to 500 wheel horsepower applications
• Includes billet aluminum and carbon fiber Lightning solenoids for fast, precise activation
• Complete kit with stainless steel braided lines, electrical wiring, switches, and all mounting hardware

This complete system provides everything needed for installation on Holley Hi-Ram equipped engines, combining professional-grade components with the convenience of a comprehensive kit. The side-injection design maximizes airflow through the runners while ensuring consistent nitrous and fuel delivery for reliable power gains across the RPM range.
