Snow Performance Stage 3.5 Boost Cooler – DI VC-100 Progressive Water-Methanol Injection Kit SNO-325
The Stage 3.5 Boost Cooler from Snow Performance delivers precision two-dimensional water-methanol injection for direct-injected and boosted engines. By mapping injection based on both boost pressure and fuel pressure sensor input, this system ensures highly accurate fluid delivery exactly when your engine demands it.
Incorporating fuel pressure into the injection strategy allows for extended control beyond traditional boost-only setups, giving tuners greater flexibility across the powerband. The VC-100 controller combines the functionality of a boost gauge and water-meth controller into one sleek unit, featuring a vivid 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) that shows boost, injection percentage, fluid level alerts, secondary stage activation, and prime status. You can match the display to your factory gauges or mix two colors for a custom look.
This kit includes the only OEM-approved water-methanol pump on the market, built with a proprietary heat flange, dual seals, and custom motor windings to run cooler and last longer. The 300 PSI UHO pump is sealed and potted to prevent moisture intrusion—unlike sleeve-style pumps that trap heat and accelerate corrosion. All components are built for durability with stainless steel, nickel plating, EPDM seals, and hard anodizing, making the system fully methanol-resistant.
Snow’s ACU-SEAL compression fittings ensure leak-free operation even with 100% methanol. Whether you're running a turbo, supercharger, or high-compression setup, the Stage 3.5 Boost Cooler helps deliver a colder, denser intake charge and elevates 91-octane fuel to race-level 116-octane performance.
Note:
Not intended for trunk-mounted setups. If mounting in the trunk, solenoid (SNO-40060) and extended feed line are required.
