This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

This fit my Mazda CX-5 perfectly. I'm happy with the seal and quality. Great price. I will certainly reorder for my next replacement.
