Snow Performance Nitrous Oxide Injection System

Snow Performance: The World Leader in Water/Methanol Injection

Snow Performance has been setting the standard for water/methanol injection technology since its founding in 2001. Based in Woodland Park, Colorado, the brand has built a devoted following among street performance enthusiasts, diesel truck owners, and motorsport competitors by engineering systems that deliver real, measurable gains in power, efficiency, and engine longevity. Today, Snow Performance is owned by Nitrous Express — one of the most respected names in performance chemistry — a partnership that has only deepened the brand's technical capabilities.

At the heart of the Snow Performance lineup is the iconic Boost Cooler water/methanol injection system. These kits work by injecting a precisely metered mist of water and methanol into the intake charge, simultaneously cooling intake air temperatures and raising the effective octane of pump fuel. The result is cooler, denser air that resists detonation, allowing forced-induction engines to safely run more boost and more aggressive ignition timing. Snow Performance offers Boost Cooler kits in multiple stages — from the entry-level Stage 1 fixed-rate setup, to the sophisticated Stage 3 systems featuring progressive electronic controllers that modulate injection based on boost pressure, MAF signal, or exhaust gas temperature data — covering everything from daily-driven turbocharged cars to hard-working diesel trucks.

A complete injection setup requires more than just a kit, and Snow Performance supplies every supporting component a builder needs. Their lineup of water injection reservoirs come in a range of sizes to suit engine bay or trunk mounting, while the brand's proprietary Hyper-Sonic water/methanol injection nozzles are engineered to atomize fluid to supersonic levels for the finest, most consistent spray pattern in the industry. Constructed from 100% methanol-resistant nickel plating, these nozzles are among the best-selling in the world. For the plumbing that ties it all together, Snow Performance offers a comprehensive selection of pipe fittings and line hardware — including their ACU-SEAL compression fittings and stainless steel braided lines engineered to handle high-pressure injection demands without leaks, even with straight methanol.

Thanks to its connection with Nitrous Express, Snow Performance also offers a line of nitrous oxide injection system kits for automotive and powersports applications, giving performance builders a one-stop source for both chemical charge-cooling and nitrous-based power adders.

Whether you're chasing more horsepower on the strip, trying to keep EGTs in check while towing, or simply want to extract more performance from pump gas, Snow Performance has engineered a solution backed by over two decades of real-world motorsport development.
