SNOW PERFORMANCE Quad Nozzle Upgrade - Proline 0.5 kg

The DNU ProLine allows an additional Boost Cooler Nozzle to be mounted in any of our Water Methanol Injection kits.

Maximum cooling performance and optimized distribution with four precision injection points

The Snow Performance Quad Nozzle Upgrade is the perfect expansion for Boost Cooler water-methanol injection systems where maximum intake air cooling, equal distribution, and high-output performance are required. Designed for builds with limited space or where a traditional intercooler setup is not used. Four precisely placed nozzles ensure consistent atomization – ideal for high-horsepower engines, motorsport applications, and demanding setups.

This upgrade includes four stainless steel braided lines and CNC-machined aluminum fittings and is fully compatible with all existing ProLine systems. Designed to connect with Boost Cooler Hypersonic nozzles (sold separately).
