Snow Performance SNO-400 Diesel Stage Boost Cooler Water-Methanol Injection Kit - 2 Dodge 5.9L Cummins

The Snow Performance SNO-400 Diesel Stage 2 Boost Cooler brings advanced water-methanol injection technology to Dodge 5.9L Cummins owners looking to lower exhaust gas temperatures and unlock additional horsepower. This complete injection system reduces EGTs by 100-300 degrees Fahrenheit while increasing horsepower by 65+ through cooler, more efficient combustion.

Progressive VC-50 Controller Technology:

At the heart of this system is the progressive VC-50 controller, a 52mm gauge-mounted unit that functions as both a boost gauge and water-methanol controller. The VC-50 features a customizable 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) that shows real-time boost pressure, injection percentage, secondary nozzle activation status, and fault codes. The progressive controller proportionally commands two water-methanol nozzles independently, injecting more or less fluid based on boost pressure for precise cooling across the engine's entire boost range. Adjustable start and full points allow you to tailor the engagement and delivery curve to match your engine's specific requirements.

Complete Stage 2 Kit Includes:

• 300 PSI extreme environment sealed UHO pump for reliable high-pressure delivery
• 7-gallon reservoir tank for extended use between refills
• Adjustable progressive VC-50 controller with wiring harness
• 20 feet of red high-temperature nylon tubing
• Dual water-methanol nozzle system with quick-connect fittings
• High-flow solenoid for precise injection control
• Boost reference line and all required hardware
• Snow Performance decal

Performance Benefits:

Water-methanol injection provides proportional cooling benefits across the boost range, improving drivability while protecting your engine. The dual-nozzle design ensures optimal fluid distribution, with the system automatically activating the secondary nozzle as boost increases. This sophisticated injection strategy delivers dyno-proven horsepower gains while maintaining cleaner, cooler operation—especially beneficial for daily drivers and light towing applications.

Designed specifically for 1994-2007 Dodge Ram trucks equipped with the 5.9L Cummins diesel engine. The quick-connect fittings and red high-temperature nylon tubing provide a clean, professional installation with excellent heat resistance.
