1. Use only genuine filters for fuel and oil. Why? They were designed by Racor, who patented them, meaning no one can copy them legally. Therefore, if it isn't in a Ford, Motorcraft, or Racor package, it likely is an inferior filter. There are few exceptions, but the easier thing to do is look for OEM filters.

2. Ditch the EGR cooler. Here's a video that tells you about some of your options: 6.0L EGR COOLER DELETE AND OIL COOLER ISSUES - YouTube
3. Get a coolant filter, pronto. The oil coolers on the 6.0 are notorious for clogging, once that happens, it starves the EGR cooler for coolant, commonly resulting in a cracked cooler, causing loss of coolant. If low coolant isn't caught by the driver, cracked heads are usually the result. A coolant filter goes a long way to prevent this.
The 6.0 is a great engine, but it has several weaknesses than can and should be strengthened. Once they are, you'll be protected from catastrophic failure.
