Modern Vespa

That is the filter that's going to be fitted (which I've since realised could be a problem for next year...)

The one that's on there is like this below but not piaggio....

The Hi Flo 197 Filter is easier to service.
That 183 does not allow good purchase due to the sloping sides that are probably required by the die. The nut on the 197 can be turned with a wrench or socket. I ran the 197 filter for 1500 miles with no issues. Due to ignorance, I replaced with a 183. Fool me once.
The 197 Filter is just a tad taller but it still clears the center stand with ease.
I don't have any data to suggest either is a better filter than OEM but they are easier to source in my area. Strap wrench first, arc joint pliers second. Hammer and screwdriver definitely last resort.

This is the kind of tool that you need: https://www.autodoc.be/neo-tools/18087490?utm_medium=cpc&utm_source=google&tb_prm=18590516782&gshp=1&gad_source=1&gad_campaignid=18593134205&gclid=CjwKCAiA64LLBhBhEiwA-PxguzpSQy54X8CExtxRfBpg_EXkRxZN7kV70z6J7S-5Uvs0dVTfUChqeBoCHy8QAvD_BwE

Select the right size.

If you put in a new filter then oil the rubber ring and srew it in hand tight. Don't put full force on it. Check if it is not leaking and it will be fine and easy to unscrew next service.
