6.4l Ford Powerstroke Coolant Filtration Kit
This coolant filtration system for the Ford Powerstroke filters a small amount of coolant with each pass. The spin on the filter makes it easy to change coolant as often as you need. Plus, the filters also remove all solid particles. Typically you will use three filters in the first nine months. Once the initial nine months has passed, you will only need to change the filter once a year.
