I never saw the oval holes ?
A third supplier?
Every supplier have to meet Ford's specification
any oil filter with Ford's name for a
specific application must have similar
characteristic so it's not a tragedy
to have different supplier for what i
know every compagnies are doing that.
Anyway if you want K&N oil filter
go to "Canadian Tires" you can have them
special order the next day for 16 or 17$ CND
