The Story
The Sinister Coolant Filter Kit is a bypass-style system that filters a small amount of the coolant on each pass. By using a standard spin on filter it's easy for you to change your coolant filter at regular intervals. These filters will remove all solid particles from your 6.7 Cummins in order to extend the longevity of your cooling system components. Typically you will use 3 filters in the first 9 months. Once the initial 9 months has passed you will only need to change the filter once a year.
