Product Details

This Snow Performance Stage-3 gasoline boost cooler kit is unmatched for accuracy and adjustability in water-methanol injection systems. It can read and inject according to either EFI fuel injector pulse-width or boost level, or any combination of both! Extremely easy to set up and dial in, the software creates a two-dimensional delivery map from just a few easy-to-set start and full points that you punch in. For an easier install and additional durability, this kit replaces your stock diverter valves with an ECS Tuning blow-off valve (BOV) to help your engine maintain consistent boost levels and smoother power across all RPM ranges. This provides a convenient location for your water-methanol injection system to tap into, making this kit a total performance solution. A BOV system will also aid in the longevity of your turbos by releasing the unwanted boost pressure during de-acceleration and in between shifts by releasing the pressure faster, keeping it from feeding back through the turbo causing damage. Not only does this kit look good, it also has the ever popular "whoosh" sound.

  •  300 psi high volume pump
  •  3 quart reservoir
  •  2 nozzles to cover a wide range of horsepower
  • 10 ft. high pressure tubing (1,200 psi burst)
