Nitrous Express 20940-10 Holley High Ram Plenum Plate Nitrous System with 10lb Bottle

The Nitrous Express 20940-10 is a complete plenum plate nitrous oxide system specifically engineered 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 that delivers direct-port-like nitrous distribution without flow-restricting nozzles or spray bars in the runners.

Advanced Plenum Plate Design:

• Precision-machined billet aluminum plate with integrated fuel and nitrous passages
• Side-injection design delivers nitrous and fuel directly into each cylinder runner
• No spray bars to break, spin, or restrict airflow
• Single-stage system with jetting for 50 to 500 wheel horsepower

Complete System Includes:

• Billet aluminum and carbon fiber Lightning solenoids for precise flow control
• 10lb nitrous bottle with new billet aluminum Lightning 500 bottle valve
• Stainless steel braided feed lines for durability
• Stainless steel bottle brackets for secure mounting
• Complete wiring harness with switches
• All necessary hardware, fittings, and connectors for installation

This system provides superior nitrous distribution compared to traditional single-point injection while maintaining the performance advantages of the Holley Hi-Ram manifold design. The integrated passages eliminate common failure points associated with spray bar systems, while the side-injection configuration ensures even fuel and nitrous delivery to all cylinders.
