Snow Performance Water Injection Reservoir

Snow Performance Water Injection Reservoirs: The Foundation of Every Boost Cooler System

A water/methanol injection system is only as reliable as the tank that feeds it. Snow Performance — the largest and oldest water-methanol injection company — designs its water injection reservoirs to be purpose-built components of the Boost Cooler ecosystem, not afterthoughts. Every reservoir in the Snow Performance lineup is engineered to work seamlessly with their pumps, solenoids, and controllers so that your fluid supply is always consistent, measurable, and secure.

Why the Reservoir Matters in a Water/Meth System

Snow Performance water-methanol injection systems cool the intake charge and combustion while acting as a high-octane fuel source. But that cooling and octane benefit depends entirely on having a properly sized, properly monitored reservoir. Run dry mid-pull on a turbocharged or supercharged application, and the consequences can range from a lost power run to engine damage. Snow Performance addresses this with reservoirs that incorporate fluid level switches and indicator LEDs — giving drivers a visible warning before the tank runs low.

Reservoir Options Across Every Build Level

Snow Performance offers reservoirs in multiple capacities to suit everything from street builds to dedicated track cars. Options range from a compact 3-quart reservoir — standard across many Stage 1 and Stage 2 Boost Cooler kits — up to a larger 2½-gallon reservoir found in Stage 2.5 systems. The 3-liter tank with separate level indicator and LED provides a straightforward in-cabin installation option, while larger-capacity tanks are favored for diesel truck applications where higher injection volumes are common.

For builders who need to maximize under-hood space or simply prefer a cleaner engine bay, Snow Performance also offers rear-mount configurations. The rear mount upgrade allows you to move the standard Snow Performance water-methanol tank to the trunk of any vehicle, and comes with 15 feet of stainless steel braided line to complete the routing. The Snow Performance High Flow Solenoid offers 100% safety for all injection systems utilizing rear-mounted reservoirs, injection points under vacuum, or installs where the injection nozzle is lower than the water-methanol tank — a critical detail when relocating the reservoir away from the pump.

Built for Methanol Compatibility and Long-Term Durability

Snow Performance systems come standard with 100% methanol-resistant components using stainless steel, nickel plating, EPDM, and hard anodizing to ensure years of continued use. This material discipline extends to the reservoirs themselves, which must hold up to the corrosive nature of high-concentration methanol mixes over thousands of operating cycles. Snow Performance's ACU-SEAL compression fittings provide guaranteed leak-free operation even when using 100% methanol.

Designed to Integrate With the Full Boost Cooler Ecosystem

Whether you're running a Stage 1 boost-switch system, a Stage 2 progressive setup, or the more advanced Stage 3 two-dimensional injection map, the Snow Performance reservoir is the starting point of a fully integrated system. Snow Performance is committed to delivering a state-of-the-art water-methanol injection experience through quality components made in the USA, expert technical support, and products that deliver outstanding value.
