I've heard of large-volume oil filters that have the same filter media, just in a bigger can. It would be good (for science!) to cut them open and find out one way or the other.

I used to run a large (Mobil M1-104) oil filter in my Subaru, but switched back to the M1-108 when I read that increasing the oil capacity also means slightly slower oil warmup. At 237,000 miles, it's looking like the body will disintegrate from rust before the engine wears out, so bypass valve behavior at startup isn't on my radar anymore.

Insulating the oil filter is a neat idea -- not having the oil filter out in the breeze ought to help things out. Have you insulated your oil pan yet?
