Gotcha!When the filter is screwed off lots of oil runs down the sides- it’s a little messy. 4cyl guys have developed all sorts of methods to catch/control the oil.
This makes it possible to use the 3.5L canister/filter, specifically the drain at the bottom- makes for a no fuss change. I’m a fan of the Jowett canister because of the Fumoto valve on the bottom, I don’t care for the plastic nipple that comes with the filter. The Jowett will work for the 3.5L too.
