It is diverted to SPEED TRIPLE.
Main looks like it is for Honda CB1300, but it fits Triumph SPEED TRIPLE.
I used to use Filtro's Filter, but if you buy in bulk at Webig, it costs less than 1000 yen per pc. and is so cost-effective that you can replace it after every Oil change.
Packing was also coated with Grease and was easy to use, so I would definitely repeat the experience.
