Even a new 6.7L Powerstroke can leave the factory with casting sand, metal particles, and machining debris in the block. That junk circulates with the coolant, wearing on the water pump and clogging the EGR cooler, oil cooler, and heater core. The Sinister Diesel SD-CF-6.7P-20 coolant filtration system bypasses a small amount of coolant through a filter while the engine runs, pulling those contaminants out over time.

A CNC-machined billet 6061 aluminum filter head, anodized in Sinister Blue, carries a genuine CAT coolant filter. The kit mounts at factory locations with no drilling, and the reinforced silicone hoses come with pre-assembled connections.

Sinister's service schedule: change the first filter at 500 miles, the second at 1,500, the third at 3,000, then at every oil change. Some aftermarket disaster prevention kits and cooling mods may interfere with this kit, and compatibility with non-Sinister parts isn't guaranteed. Verify fitment for your truck before ordering.
