Let's get the current knowledge of what oil filters work on the Twins compiled, and we'll replace the current sticky which is silly long. I'll do my best to keep this top post updated and keep this thread fairly clean.
Filters reported to work:
HIFLO-FILTRO HF204
NAPA 1358 and Wix 51358 (same thing, about 1/4" longer than OEM)
Ryco Z436 (Australian brand?)
Mobil motorcycle-specific M1MC-134 (discontinued)
Purolator motorcycle-specific ML16817
Mobil M1-108 and M1-108A (and longer M1-110) - redesigned around 2020 and is now about 1/2 to 3/8 inches taller than OEM
A/C PF2135
Amsoil SMF-103
Baldwin B1400
Bikemaster 171632
CARQUEST 85358 (same as the NAPA 1358/Wix 51358?)
Fram. PH6017S
Hastings LF113
MAHLE OC 575
Filters to be wary of:
K&N KN-204 and KN-204-1 - There are lots of reports of these leaking at the weld for the nut, and they've been banned at some tracks because of it. See for instance K&N Oil Filter Mishap- Oil Filler Cap, Another k&n 204 horror story w/Scramber, K&N 204-1 leaking oil filter
NAPA 1365 and Wix 51365 - don't fit anymore, see NAPA 1365/1358 oil filter
Purolator PL 14612 and longer 14610 no longer fit after redesign in 2015: Defective Purolator Filter
Bosch 3300 - recent problems with these too: Bosch 3300 Oil Filter No Longer Fits Our Bikes
Ryko Z445 also doesn't tighten up fully.
This thread replaces the one at Oil filters that fit, which got too long and silly by the end, and had to be locked.
