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.
