Sinister Diesel Universal Coolant Filtration Kit with WIX Filter
Make coolant filtration part of your diesel truck’s maintenance routine. The Sinister Diesel Universal Coolant Filtration Kit uses a WIX coolant filter to help capture casting sand, metal shavings, rust and mineral deposits, reducing debris that can contribute to cooling-system wear and blockage.
Designed for compatible Duramax, Powerstroke and Cummins applications, the kit brings together a billet aluminum filter block, hose barbs, silicone hose and mounting hardware so you can plan an installation around your truck’s cooling-system layout.

Check compatibility before ordering
This is a universal kit, not a vehicle-specific fitment guarantee. Confirm your coolant hose sizes, available mounting space and routing requirements before purchase.
Filter maintenance
The supplied manufacturer guidance recommends replacing the first filter after 500 miles, then replacing the second and third filters after 3,000 miles each. After those three changes, replace the filter annually.
