Snow Performance SNO-2169-BRD Stage 2 Boost Cooler Water Methanol Injection Kit for BMW N54/N55

The Snow Performance Stage 2 Boost Cooler Water Methanol Injection Kit is specifically engineered for BMW N54 and N55 turbocharged engines, delivering direct port injection for maximum performance gains and detonation protection. This comprehensive system safely increases boost pressure while dramatically lowering intake air temperatures, allowing for more aggressive tuning and improved engine reliability under high-load conditions.

Key Features:

• Direct port injection design delivers water/methanol mixture precisely where it's needed for optimal cooling efficiency
• Stage 2 Boost Cooler controller with progressive injection mapping tied to boost pressure
• Dramatically reduces intake air temperatures by up to 100°F, preventing heat soak and detonation
• Allows for more aggressive timing and boost levels while maintaining engine safety margins
• Complete bolt-on kit with all necessary hardware, lines, nozzles, and mounting brackets
• Includes high-quality reservoir tank with low-fluid warning system
• Compatible with both gasoline and E85 fuels
• Proven to support 100+ horsepower gains on modified turbo applications

Water methanol injection is one of the most effective power adders for forced induction engines, providing both performance enhancement and critical engine protection. The Stage 2 system's progressive injection ensures you're only using fluid when you need it, maximizing efficiency and minimizing refills. Professional installation and proper tuning are recommended to achieve optimal results.
