The oil filters for the WRX are by far, the smallest I have seen.
For a turbo 2.5L engine that has a sump of 4.4 qts and a OCI recommendation of 7500 miles, I would expect a larger filter. . . .
This just seals the deal for me in my desire to change the oil every 3000 miles.
My finger touching the base of the filter:
That's one and a half inches of filter length!!!!
