So then how on earth would those larger diameters work on a Yaris? It's not maybe, they'll fit, they have actually been used. @Tkonrr is not the first guy to verify they're ok.
If you do a search you'll see at least one or two other verified examples. The diameters don't have to be exact, they just have to fit on the filter boss unless yours is smaller than all
Toyotas.
All depends on the flange? Our Camry takes the 4967 sized filter and a 3614 equivalent will not fit, gasket diameter is too big. Likewise on my mower that takes a 3614 sized filter the 4967 gasket size will cover up the supply inlet. So, this has been my experience.
I feel like this all is trying to solve a problem that does not exist. But, it's not my equipment to blow up.
