Nitrous Express 15126 Direct Port Water/Methanol Injection System 6-Cylinder Stage 2

The Nitrous Express 15126 is a direct port water/methanol injection system engineered for 6-cylinder applications. Unlike throttle body or intake manifold injection, this system delivers the water/methanol mixture directly into each individual intake runner, ensuring precise and uniform distribution to every cylinder for maximum charge cooling and detonation resistance.

This Stage 2 system features a digital progressive controller that dynamically manages water/methanol output based on engine demand. Controller output is conveniently adjusted using rotary dials on the progressive control box, making tuning straightforward without the need for a laptop or external device. The system uses manifold boost pressure as the trigger signal to determine injection timing and volume.

What's Included:

• High-pressure electric pump
• High-pressure push-lock hose
• Filtered nozzles (one per cylinder)
• Nickel-plated fittings
• Composite fluid reservoir
• Digital progressive Stage 2 controller with rotary dial adjustment

Stage Comparison:

• Stage 1 — Wide-open throttle (WOT) activation switch; on/off control
• Stage 2 (this kit) — Digital progressive controller; output adjusted via rotary dials on the controller box
• Stage 3 — Digital progressive controller with LCD display; fine-tunable for low, mid, and high airflow levels; displays boost pressure, injector duty cycle, and water/methanol injection percentage

The Nitrous Express direct port design is the preferred solution for performance and forced induction builds where cylinder-to-cylinder consistency is critical. Whether used for intercooling, detonation suppression, or power enhancement on turbocharged, supercharged, or nitrous-assisted engines, this system delivers reliable, tunable water/methanol injection at the source.
