The XP seems to use a different bypass design than the non-XP 57356. The non-XP has an extra ring thing for they bypass, and it takes up so much space, resulting in a tiny media cartridge. This means that the regular Wix has less media than the XP in this size.
Is each OCI the one suggested by the minder?
Was the 12k OCI first, then the 9k OCI? What kind of oil did use, and what did you replace it with?

No, the oil is changed before the OLM says it's time. The oil gets changed to XW-30 in the summer for track days and 0W-20 over winter when the car doesn't see the race track. However, the filters are always used for two oil changes like Honda recommends.

Looks like the 9k was actually first. The car was filled with Castrol Edge 0W-30 for track/summer and Kendall GT-1 Max 0W-20 otherwise.
The filter was replaced with a Purolator Boss this time but filled with Kendall 0W-20 again.
