A Big Improvement over OEM
If you're going to go to the trouble of replacing the Housing/Cooler assembly it pays to use the Aluminum Dorman version. Everything I needed, minus the sensors (which get swapped for the original part) was included. A couple of YouTube videos showed how to get to part and Dorman gives instructions on completing the swap. Removing and installing the upper intake manifold was BY FAR the worst part of the operation.
Don't buy one of the off-brand knock-offs. Only the Dorman version is made in the USA.
A helpful hint for working on a Grand Cherokee: Take the 10 minutes to remove the windshield cowl and upper shield. The extra room is a big help.

One off?
Installed after the plastic one atarted leaking. I was impressed at the quality and improvement initially. After it was installed no oil preasure. After some investigating the port for the oil pressure sender was not machined all the way through. Was able to drill the hole out carefully because i was in a pinch but should not have been an issue in my opinion. Maybe it was a one off but who knows.
