This is sort of an odd discussion, because most Mitsubishi vehicles take the same oil filter according to WIX. When I look up a Mirage oil filter on the WIX site, I can also see what vehicles use the same filter (57356 & 57356XP). All of these vehicles are listed for their 57356/57356XP oil filter. I copied & pasted from their website below.

Several Acura, Honda, Infiniti, & Nissan vehicles use this same filter, too! A few Mirage owners own an Outlander Sport, & I would assume they buy the same oil filters for both vehicles.
Since their entire lineup basically uses the same oil filter, it seems very odd that a Mitsubishi dealership would get it wrong or be confused?????
Or this just confirms this particular Mitsubishi dealership is retarded (like Fummins clearly stated).
If I were you, I would asked them what filter fits another type type of vehicle like an Outlander or Outlander Sport. If you look at the list, it doesn't even matter what engine it is. Mitsubishi's 1.2L, 1.5L, 2.0L, 2.4L, & 3.0L engines all use the
SAME oil filter.
Cobrajet & you discussed this before (posts # 5 & 6), but not sure any real conclusions were made -
