The Tefba is a full flow filter and filters nowhere near as fine but it's better than nothing. Easy install and very easy to clean.
TP filters are depth filters in that oil is slowly forced through the entire roll in contrast to a full flow surface filter. That's why a depth filter must be used in bypass mode. It could never flow enough to feed the engine. On the other hand it's the depth filtration and slow flow that cleans the fluid being filtered so well.
Mine is sourced off a sandwich adapter and returned through an orifice to one of the hex plugs in the #3 cylinder cover. What's interesting about the set up is *all* the oil my engine receives, other than the tiny amount going through the filter that gets dumped to the head, has to go through a single 1/4 inch hole in the sandwich plate.
Dub: The real looks come when cruising the supermarket TP isle opening packages and measuring rolls. I also prefer Scotts 1000. It's wound tighter than Frank on a bad day (j/k Frank) but institutional stuff is great too.
