Fits 2010 Subaru Forester with 2.5 non-turbo
Definitely looks and feels like a better than OEM air filter. Not sure of any other benefits.

Good Quality, Good Price for a Subaru Replacement Air Filter
Look like a great name brand filter. Not a bad price for a Subaru (2013) replacement. I will buy again if available.
