Dual Nozzle Upgrade

The Dual Nozzle Upgrade is a precision water injection component designed for advanced methanol and water-based cooling systems used in high-performance engine tuning. Built for enthusiasts and professionals running Snow Performance water injection systems, this upgrade replaces or enhances single-nozzle configurations to deliver dual-point fuel charge cooling across intake runners or cylinder heads. The dual-nozzle design enables more uniform heat absorption and improved detonation control, making it essential for turbocharged, supercharged, and naturally aspirated engines pushing beyond stock parameters.

This upgrade features a fitting and hose-compatible design that integrates seamlessly with existing water injection kit plumbing. The dual-nozzle configuration allows simultaneous injection at two strategic points, maximizing spray dispersion and minimizing fuel vaporization losses. Each nozzle is precision-engineered to atomize the water-methanol mixture at optimal pressure and droplet size, ensuring consistent cooling performance under sustained boost conditions. The compact 4.4 x 3.45 x 4.85-inch footprint and lightweight 0.35 lbs construction make installation straightforward on both OEM and aftermarket intake manifolds without requiring extensive modification.

Engine builders, tuners, and serious performance enthusiasts benefit most from this upgrade when stepping up to higher boost levels or racing applications where single-point injection falls short. Real-world use cases include street-legal turbocharged vehicles targeting 400+ horsepower, competition drag and road-race engines, and platform-agnostic builds where maximum charge cooling is critical. The Dual Nozzle Upgrade is compatible with standard Snow Performance water injection system hose and fitting specifications; verify your kit generation and nozzle mounting location before ordering to ensure proper fitment and optimal performance gains.
