Sinister Diesel introduces new coolant filtration systems for 6.0L and 6.4L Ford Powerstroke and 5.9L and 6.7L Dodge Cummins engines. Sinister says its new coolant filter kits are unique from other brands in a number of ways. First, they are easier to install than other kits. In addition, the kits use stainless-steel lines rather than rubber. Of course, they also feature the distinctive Sinister Blue color. The coolant filter systems keep coolant galleries clean of rust and debris, which prolongs oil and EGR cooler life, utilizing an easily obtainable spin-on filter. Increased water pump life is also a huge benefit from this kit.
