Anyone have any recommendations on a source for the part? I found one one ebay for $220 shipped. Not OEM, "genuine" branded - my guess is chinese manufactured. Only one I've found so far that I KNOW is for my car (with oil cooler).

You can get an OEM for less than that.

Double check your model code.

Just need the baffle plate.

Thanks, already had an account there. Don't know why I didn't think of them.
