Upgrade the Oil Cooler in your 2003-2007 Ford 6.0L Powerstroke with the XDP 6.0L Heavy Duty Oil Cooler XD212. The factory Oil Cooler is a single component that is responsible for many issues on the 6.0L. Often plugged or blocked from existing contaminants and debris in your cooling system, the oil cooler can quickly lose its ability to properly cool the oil in your Powerstroke engine.
