Diesel Stage 3 Boost Cooler – Universal, No Tank (SNO-50100-T) - Turbo Diesel Applications
Tow cooler, pull harder—50-state legal. Snow Performance’s Stage 3 Diesel Boost Cooler is built for turbo-diesel owners who see heavy loads and soaring EGTs. Its 2D-mapped controller blends boost and EGT to command precise water-meth delivery, helping cut exhaust temps by ~100–300°F, clean up emissions equipment, improve fuel economy, and add up to 65+ HP under load. This “No Tank” SKU lets you use your existing reservoir or pair with your preferred Snow tank.
Key Benefits
- Colder, safer towing: typical 100–300°F EGT reduction helps protect pistons, turbos, and aftertreatment.
- Real-world power: up to 65+ HP potential for easier hill pulls and passing.
- Cleaner operation: reduced soot, cleaner intake/combustion components, and improved drivability.
- Warranty-friendly: system does not leave a tuning signature on the vehicle.
