Works in 2019 Subaru Outback!
If you are looking for an engine air filter to fit in your 2019 Subaru Outback then look no further -this one will fit. I tried two others that would not allow me to close the compartment door with the latches. This one slipped in like a hand in a glove.

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.

It works!
Fitment was great on my 2014 Subaru Crosstrek. Construction was solid and great that I don’t have to worry about changing it for 18,000 miles. Would purchase again.
