OEM quality
Great alternative to OEM, worked great on 18 outback 2.5. Should fit most 2.5/2.0 Subaru engines in various cars.

Just Get the Premium
Overall dimensions are slightly smaller than OEM. Purchased this and then found the BOSCH Premium equivalent for less (both here on Amazon). This one works fine, but for less money and better filtration, just get the Premium line.

Great oil filter
This oil filter has long life and does an excellent job. It’s easy to hold for installation and removal. The seal doesn’t come off of the filter to accidentally double gasket.
