2013-2018 Cummins 6.7L Sinister Coolant Filtration Kit (SD-6.7CCF13-01-20)
Add years of life to your 6.7L Cummins with the Sinister Diesel Coolant Filtration Kit. When your engine was built, leftover casting sand and metal shavings from the casting and machining process can remain in the cooling system, where they wear down your water pump, engine oil cooler, and EGR cooler (if equipped). This kit bypasses a small amount of coolant through a filter while the engine runs, removing those contaminants and helping these critical parts last longer. The filter boss is CNC machined from billet 6061 aluminum with an anodized finish and features 2 threaded inlet ports and 1 outlet port. It attaches to the supplied bracket, which mounts to factory holes in your Ram chassis. All fittings are included, the silicone hose fittings come pre-assembled for simple, leak-proof connections, and everything is factory tested at twice the recommended radiator cap pressure. When it’s time for service, the filter simply unscrews for easy replacement.
