BPD stood by their product to the fullest extent, didn't cover 100% but was taken care of to the owners satisfaction. I have the upgraded design Ford oil cooler and did a thorough coolant flush and did switch(even though that "switch" is quite the debate anymore) but having clean coolant and a coolant filter is the key..my EOT ECT deltas have yet to exceed 4* even sitting in traffic. IMO, I would spend the money on Dougs intake for the delete and EGT control...if it was available at the time I did my studs and deletes, thats what I would have done after now seeing testimonials of owners of Doug's intake.
Cleanliness is essential when working on the 6.0L. The engine isn't known for it's fault tolarance. Any debris that enters the oiling system during the install of either our kit, or completely stock parts could have the same effect. In other words, it could be the straw that breaks the camel's back. Consider that most(~90%) of the HPOP filter screens we remove during the course of the repair have been compromised before we even touch the vehicle. That debris and filter element went someplace right? How about straight into the HPOP, IPR valve, and injectors.
Having said all that... Doug does make some very cool stuff
The semi bullet proof kit is a short term fix for SOME known problems. Our full kit is a solution for MOST oiling related pattern failures. We test our kits and ideas in the city of Phoenix. You know... The surface of the sun. And we test our products under extreme use in the deserts of Arizona, Nevada, California, and Baja. Our full kit was designed to meet or exceed the factory oil cooler specifications while increasing reliability and longevity of the 6.0L.
