Whilst it is too early to call it super deep I have to say I am more than happy with the performance of this oil cooler at the moment. I have '04 6.0 with ok. After driving it 245,000 miles, I noticed my temperatures on my BullyDog programmer were slightly higher than normal for several weeks. I then towed the trailer two weekends in a row and noticed a slight loss of coolant, nowhere but at the radiator. I've heard some horror stories about the oil cooler so I thought sooner rather than later. I have about 1500 miles on this new radiator and so far so good. My oil temp has only exceeded 200F once, and that was on a sunny day at 75mph up a steep hill. I was skeptical about buying this cooler, thinking it was too good for the process to be true, but so far I'm satisfied.
