WRX Oil Filter Dissection
Disassembly and inspection of the original oil filter after the
engine's first 3000 miles.
The exterior of the OEM filter
showing all external markings.
The disassembly and what's inside.
This is a sample of what drained out of the
filter. Some of these particles were ferrous metal and attracted
to a magnet but most of it is dirt and sand. Also recovered from inside
the filter was a fairly large metal shaving (~1/2" long),
unfortunately it was lost before it could be photographed.
