What you have all said makes sense to me. A cheaper replacement for a bad 3.2 using the original intake tubing and throttle body. I'll measure the oil cooler and get a better look this afternoon. The engine looks pretty clean except for where the oil has leaked down near the AOS, so probably a relatively recent swap.
Funny, I've seen lots of base models on Craigslist that were trying to be an S. Now I have the S, trying to be a base.
The good news:
