Mishimoto Coolant Filter Kit
2003-2007 6.0L Ford Powerstroke
The oil cooler on the 6.0 has a tendency to clog on the inlet side due to particulates building up in the coolant that feeds the filter.
Prevent a needless oil cooler replacement with this simple-to-install bypass coolant filter kit from Mishimoto. The no-crimp hose design ensures many years of trouble-free use and the shut off valves allow easily isolation of the filter for mess-free filter changes.
Hoses are available to color coordinate your under-hood look in black, blue, and red.
