Snow Performance Water / Methanol Injection Nozzle

Snow Performance Hyper-Sonic™ Water/Methanol Injection Nozzles

When it comes to water/methanol injection, the nozzle is everything — and no one has engineered this critical component more carefully than Snow Performance. Their flagship Hyper-Sonic™ nozzle line has earned a reputation as the industry benchmark for atomization quality, durability, and versatility across forced-induction applications of all kinds.

At the heart of the Hyper-Sonic™ design is a patented internal geometry: the nozzle spins fluid to supersonic velocity before forcing it through two venturi-shaped orifices, producing an ultra-fine micron droplet mist. This physics-driven approach matters because, as the principle of heat absorption dictates, smaller droplets mean a greater total surface area per volume of fluid injected — translating directly into more aggressive charge cooling with less fluid consumed. The result is denser, cooler intake air and a meaningful resistance to detonation under boost.

Construction and Material Quality

Snow Performance builds these nozzles to survive the chemically aggressive environment of methanol-rich mixtures. The body is constructed from 100% methanol-resistant stainless steel with zinc or nickel plating, ensuring long service life even in high-duty-cycle applications. Each nozzle ships with a removable 80-micron inline filter that protects the precision orifices from particulate contamination and can be cleaned and reinstalled, making the nozzles fully reusable across multiple builds or vehicles. Thread sizing is standard 1/8" NPT, compatible with Snow Performance's own nozzle holders and most aftermarket mounting solutions.

Wide Range of Flow Rates for Every Application

One of the most practical advantages of Snow Performance's Hyper-Sonic™ nozzle lineup is its exceptionally broad sizing range. Available flow rates span from as low as 30 ml/min all the way up to 750 ml/min at 100 psi — giving tuners and enthusiasts the granular control they need to dial in injection volume precisely to their engine's fuel flow, boost level, and fluid mixture ratio. Common sizes include 4, 6, 7, 8, 10, 12, 14, 16, and 25 GPH variants, covering everything from mild street builds to high-horsepower track and competition applications supporting well over 1,000 hp.

Drop-In Upgrades and System Compatibility

The Hyper-Sonic™ nozzles are engineered as direct replacements or upgrades within Snow Performance's own Boost Cooler® Stage 1 through Stage 4 kit ecosystem, but their standard 1/8" NPT threading also makes them compatible with most third-party water/methanol injection systems. Whether you're refreshing an existing setup or building a custom direct-port injection configuration from scratch, the Hyper-Sonic™ nozzle is designed to be a straightforward swap that immediately improves atomization quality over older-generation designs. Flow rates are calibrated and referenced at 100 psi pump pressure, making sizing math consistent and predictable.

Why the Nozzle Makes the Difference

Many water/methanol injection systems are limited not by the pump or controller, but by the nozzle's ability to fully atomize the fluid before it reaches the combustion chamber. Snow Performance's Hyper-Sonic™ technology directly addresses this weak point, producing up to 20 finely atomized veils of mist that saturate the intake charge uniformly. For anyone running a turbocharged or supercharged engine looking to extract maximum cooling efficiency and detonation resistance from their injection system, upgrading to — or starting with — a Snow Performance nozzle is one of the highest-value changes available.
