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.

Fit perfectly in the filter box, looks well built as far as gas improvement its to early to tell, car drove fine with is installed but it was just installed last night and I have only driven it 30 miles since the install!! I will update if it changes but the price sold me on this along with other reviews! I would buy again at this point!
