Snow Performance Chevy/GMC Stg 2 Boost Cooler Water Injection Kit (SS Braided Line 4AN Fittings)

The stainless steel braided lines and 4AN fittings on this Snow Performance Stage 2 Boost Cooler kit mean you're getting a well-built system designed for serious diesel performance. This kit is made for Chevy and GMC Duramax trucks, specifically models like the LBZ, LLY, LMM, LML, and L5P. It's designed to lower exhaust gas temperatures by up to 300 degrees and can increase horsepower by over 65, all while keeping your engine running cleaner and cooler.

At the heart of this system is the progressive VC-50 controller, which also functions as a 52mm gauge. This advanced controller lets you fine-tune when and how much water-methanol mixture is injected, based on your boost pressure. You can set the engagement and delivery curve to perfectly match your engine's needs, ensuring accurate delivery for improved drivability and performance across the entire boost range. The controller features a 7-color OLED screen that displays boost levels, injection percentage, secondary nozzle activation, and even fault codes, allowing you to customize it to match your dash or personal preference.

This kit includes dual water-methanol nozzles, a high-flow solenoid upgrade, and a check valve to ensure consistent and reliable operation. The large 7-gallon tank means you're ready for longer trips, making it ideal for daily driven Duramax trucks that do some light towing. Everything is made in the U.S.A., giving you confidence in the quality and reliability of this water-methanol injection system.
