Just did the first oil change on out 2020 CX-5 GTR. Found the factory installed filter to be be larger than the one provided by the Mazda dealer. Putting up some photos, hoping that there is a simple explanation. Factory installed is on the top. Thanks in advance.

Factory installed oil filters on SkyActiv 2.5T and 2.5L are Japanese made Tokyo Roki PY8W-14-302 and PE01-14-302B respectively.
PY8W-14-302 had been available since 2016 for 2.5T in gen-2 CX-9, but got superseded by Thai made Denso 1WPY-14-302 oil filter in 2019.
PE01-14-302B has never been available in the USA. An earlier version Tokyo Roki PE01-14-302A was available for 2.5L until 2016, and also got superseded by Thai made Denso 1WPE-14-302 and a value line Mexican made PE01-14-302A-MV oil filter.
And yes, both OEM Denso 1WPY-14-302 and 1WPE-14-302 oil filters are physically smaller in diameter than factory Tokyo Roki filters. This’s Mazda Norrh American Opetations’ decision importing Denso oil filters from Thailand, apparently for cost reason.
Smaller size on OEM Denso oil filter also makes oil level a bit higher with the same amount of oil for the oil change.
