I went with a Harley oil cooler and installed it myself. It isn't difficult but there are some catches. You have to have a 7/16" allen wrench or allen socket to remove the old adapter. You also have to move the voltage regulator up and take the front motormount loose to mount the cooler. None of this is hard in itself but all together it is a bit of a pain. I could immediately feel the motor run cooler in traffic. If you are going to do a lot of performance mods, I think it is a good idea.
I also have the Harley oil cooler. Regarding the install, the best thing you can do is ignore the assembly order in the instruction sheet. There's very little room to work and you will drive yourself insane following the assembly order in the instructions. You will need to get some gasket sealer/glue to stick the gasket to the cooler adapter. As for the 7/16" allen, I used a 5/16" coupling nut. It has a 7/16" hex OD and is about two inches long. I haven't ridden enough since I installed it to determine how well it works.
