Description:
The Sinister Diesel Coolant Filtration Kit is the best insurance you can buy for your 6.7L Cummins. The factory cooling system allows casting sand, rust, and metal debris to circulate, which clogs the heater core and shortens the life of vital parts like the water pump, oil cooler, and EGR cooler. Our kit solves this by continuously filtering small amounts of coolant while the engine runs, trapping harmful contaminants before they do damage.
Engineered from CNC-machined billet 6061 aluminum and finished in signature Sinister Blue, this system is built to last. It mounts directly to factory holes (no drilling required) and comes with reinforced silicone hoses that are pre-assembled for leak-proof connections tested to twice the normal system pressure. Maintenance is simple: replace the first filter at 500 miles, the second at 1,500 miles, and then every oil change interval thereafter.

FAQ's
- Q: What is the installation time for this product?
- A: The Sinsiter Diesel Coolant Filer Bypass system takes approximately 2 hours for installation. Installation time may vary based on experience.
- Q: Why do I need a Coolant Filtration system?
- A: From the factory, many engine blocks will have sand, from the casting process, still in the cooling channels. If not filtered out, the sand can clog EGR coolers or cause premature wear of water pumps or coolant seals. Our Sinister Diesel Coolant Filtration System is a stylish and affordable "insurance" against premature failures from debris in the coolant system.
