What Oil Filter for M20S

[mooneyflyer]

Do folks use 48109 or 48110-2?

I ordered the 48109-2  because I think that is what is on there.      But the application guide on Spruce says 48108 for the Ovation.   I don't recall there being a clearance issue.    There there is this letter.

The 48110 is used on the Lycoming engine on the Bravo. 

If you have enough room on your Continental the 48109 is bigger and has more filtering material, but the smaller 48108 is also approved.
