On my R3T I use only genuine Triumph or K&N oil Filters, and a great Aussie oil Penrite Racing 15 Full Synthetic PAO Ester 15w -50 Full Zinc, change every 8000Ks ,BTW 8 oil changes and I haven't had to change the O rings yet, 45000Ks fingers crossed only a water pump replaced so far
Should be a chrome cover to protect a standard spin on filter like below
Anthing else is after market. As for oil I would run mobile 2v4rt 15w50 as the transmission seems to like it. There are many good oils out there. Rotella well if I had dome I would use it to start the burn pile.
Since your in the USA Penrite would have to be imported. If mine were stock and I wanted to try something other then the mobile 1 I would lean towards AMS oil 20w50 motorcycle oil, Red Line 20w50 motorcycle or Motul 300V 15w50 motorcycle grades all are Ester oils. But this is just my opinion.
Thanks to everyone for the quick and detailed responses! Based on this info, it does look like an aftermarket filter. I should have posted this photo to start with:
