Removed from my 2007 Ford F-350 today. These combo filters were run 15,689 Miles & 342.4 Hours.
There was some rusty crusty stuff behind the water filter screen which is somewhat surprising considering how chunky some of the particles were. Primary is a 10 micron & Secondary filter is 4 micron rated.
