Ran this filter 5000 miles in my 2011 WRX. This is an "oversized" filter for the application. I was looking for whether heat from the nearby exhaust components could be "coking" the oil.
I cut it open with tin snips.
UOA is also posted over in that section.
Previously, this car has had oil changes at the recommended 7,500-mile intervals. I'm re-thinking that after reading a well-respected Subaru mechanic in the Seattle area's claims that the newer Subaru oil filter is too small to operate that long. I am now running the Fram Ultra, and want to make sure it stays free-flowing since the bypass pressure is lighter than Subaru spec.
