6.0 EGR cooler.

The root cause of the egr failure is the coolant circuit of the oil cooler clogging up and starving it for coolant making the brazing melt inside the egr cooler and leak. The oil cooler clogs due to the coolant/casting sand whatever you want to call it. Coolant does double duty on diesel motors and must be changed more often than 100k as origionally advertised. My personal experiences are from working on them at the dealership. My boss had one, now owned by his dad. Drained and refilled coolant every 30k and no problems with the truck. His brother has a newer 6.0 and did no maintenance other than oil changes and began having all kinds of problems at 80k miles. I do like the tube type egr cooler though the look like they are welded at the ends and not brazed.

The one's I have looked at are stainless steel and are tig welded. Looks like a good setup. I will go ahead and change the oil cooler also.

Yes I had the BPD one installed along with the OEM oil cooler. Runs fine, have no issues. Guy that did work was lead tech at a ford dealer, he also brought my truck up to date with the latest TSB's. 8-9* spread when cruising at 80 mph empty. I think there are several company's offering improved coolers, just depends on which one you want. While the guy was working on the coolers I had him do head studs and gaskets at the same time. I also changed over the caterpoillar ELC coolant and got away from the ford gold which is still thought as being the reason there were failures in the coolers.
