You're right, that's what it's for.

Anything that's slightly compressible and will take the heat and oil
should be fine.

As long as most of it is still intact, it should do the job.

Sounds like your OE stuff is still okay, but the felt should work
too, as long as it doesn't put much force on the cooler when the tin
compresses it. Whatever you do, make sure it's glued securely in
place.
I have really good polyurethane foam that is better than the OE if
you're not sure about what you have.
