Text Describing the Image

Sinister Diesel’s popular Coolant Filter Kits are now available for 2001-2015 Chevy Duramax trucks!  These kits are designed to remove large and small debris from the cooling system, prolonging the system’s life by keeping harsh minerals and particles from heating up seals and building up scale in the engine.

These kits are easy to install and include all the hardware you need. In addition, the coolant filter block is anodized Sinister Blue for a custom look under the hood.
