Did a full buuletproof on my 2006 ford F350 6.0 Powerstroke and opted for the factory cooler. It is what it is. A poor design from Ford, but way better than the aftermarket junk. I did not have the money for the Bulletproof Diesel air oil cooler upgrade, so I had to go this route. A few hundred miles after the complete job, temps seem to be in line again (7-9 delta, EOT at or under about 200 degrees most of the time), so I am happy. Just praying this stupid thing does not clog again! But, Riff Raff was awesome and the price was unbeatable, at least while I was researching this. My shop wanted to sell me a Dorman (CRAP) for that same price I paid for this OEM unit. Riff Raff was awesome.
