1) Is it possible that the 03 coolers had a lower failure rate because of something other than design? Is it possible that something else in the manufacturing process changed that led to an increase in cooler failures? For example: Is it possible that a manufacturing process changed which led to an increase in debris (casting sand) in the cooling system which in turn led to an increased rate of failure in later models - a failure rate unrelated to a change in design?
2) Why did navistar change the cooler design?

I don't disagree with that statement one bit. The whole reason for the design change mid-2004, was to improve EGR cooling efficiency and thus further reducing NOx emissions.
You know, if I were ever able to afford to buy (let alone own and maintain) one of these trucks, I wouldn't be adverse to trying out one of these coolers. I have to admit, they do look very beefy inside. My only question would be if it cools EGR gases as efficiently as the OEM ones. Unfortunately, working as a dealer tech at my meager income, I'll never be able to buy one to know.

My oil cooler is original and the truck is going on 9 years old this year. Temperature spreads still hold in the winter within 2-3 degrees and 5-6 in the summers. That tells me there's not even a hint of any clogging. No coolant filter, I would like to find out the oil cooler failure rate of the early 6.0 trucks.

my first flush was at 70000 wish I caught it sooner
I have plugged one filter since the flush but when I cut It open I didnt
find much allittle black sand and no goo kinda surprised it was plugged after what I saw. that filter had 4000 on it. Ill see what I find on the filter in a week.
so at 75000 Im at a 25 degree spread everytime I shut it down after a good drive its been this way for a year that I know of.
still original EGR cooler too

I just spoke with a mechanic at a local Fleet/ Diesel repair and maintenance shop. I was discussing some issues with my truck and the topic of egr coolers came up as one of the more common problems on the 6.0 , and he told me that Ford had just come out with a new and improved egr cooler that was supposed to be less problem prone. They claim to work on quite a few powerstrokes.

There was some discussion about whether the BPD unit cooled as efficiently as OEM and IIRC Ken said that they didn't, but I don't remember the exact technical explanation that he gave. BPD is pretty dilligent about all aspects of their work. Maybe he'll pop in and revisit the subject.

To be fair, I just recently did a set of head studs for a fellow member's 2004 F-350 late-build, with 220,000 kms. on the clock that still had the orginal square type cooler intact (original orange hose and all), and not even a hint of coolant leak from either the hose or the core of the cooler.

Did you flush regular from the start
my first flush was at 70000 wish I caught it sooner
I have plugged one filter since the flush but when I cut It open I didnt
find much allittle black sand and no goo kinda surprised it was plugged after what I saw. that filter had 4000 on it. Ill see what I find on the filter in a week.
so at 75000 Im at a 25 degree spread everytime I shut it down after a good drive its been this way for a year that I know of.

I changed the original coolant in the summer of 2008 at 102,000 last summer I had the Ford dealer VC9 flush it and new coolant at 130,000 I put a Edge Insight on in 2009 and temps are holding very close in the spread.
