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.
