If you are using one of the many tricks (plastic bag, molded funnel) to capture and drain the oil filter towards a pan when you remove the horizontal oil filter, you might be interested in this:
It fits onto the existing oil filter mounting, and allows you to pivit it so that the oil filter points down. It's pricey though at around $84.00. I think I saw another site selling it for $79.00. It also looks like it replaces the FL500 filter with a larger FL1 filter.
If I get a load of cash burning a hole in my wallet, I may buy one, as it seems every one out of two oil filter removals, I drip some oil onto a mat, or on the frame/crossmember.
I saw a cut-away engine at a show recently of a 3.7 V6 that had a vertical oil filter. I think it had one of these installed.
