Sinister Diesel 03-07 Dodge 5.9L Cummins Coolant Filtration System w/ Wix Filter

The Sinister Diesel Coolant Filtration System is designed to clean coolant and extend engine life for 2003-2007 Dodge Ram 2500/3500 5.9L Cummins models. It removes microscopic particles like casting sand, metal shavings, and rust that can cause premature wear and damage to water pumps, EGR coolers, and oil coolers. This system ensures your cooling system operates at maximum efficiency.

The filter block is constructed from anodized aluminum and includes a mounting bracket that attaches to factory holes, requiring no drilling. It features silicone hoses and comes with a WIX coolant filter. Regular filter replacement is recommended: at 500 miles for the first change, then every 3,000 miles for the next two, and annually thereafter.
