Nitrous Express 15130H Direct Port Water Methanol Injection Kit Cylinder Stage - 4 3

The Nitrous Express 15130H is a premium direct port water methanol injection system engineered for 4-cylinder engines. This Stage 3 system injects the water-methanol mixture directly into each intake runner, ensuring optimal distribution to every cylinder for maximum cooling efficiency and performance gains.

Complete System Includes:

• High-pressure electric pump for consistent delivery
• Stainless steel hardlines for durability and precise routing
• Filtered nozzles for reliable operation
• Nickel-plated fittings for corrosion resistance
• Composite reservoir tank
• Stage 3 digital progressive controller with LCD display

Stage 3 Controller Features:

• LCD display screen for real-time monitoring
• Displays boost pressure and fuel injector duty cycle
• Shows water-methanol injection percentage
• Finely adjustable control for low, mid, and high airflow levels
• Progressive activation for smooth power delivery

This direct port design eliminates the distribution issues common with single-nozzle systems, providing each cylinder with precisely the right amount of water-methanol mixture. The Stage 3 controller offers the most advanced tuning capability in the NX water methanol lineup, allowing you to optimize injection rates across the entire RPM and boost range for superior charge cooling and detonation suppression.
