Awesome product!
Size: 1" x 1" x 1"
Awesome product! Fit just as it should. A lot better then buying the replacement ones every time I do an oil change. I drive a mile of gravel roads everyday and this helps keep the dust from coming into the vehicle.

Fit my Subaru Forester perfectly!
This fit my 2024 Subaru Forester perfectly. The filters exhibited a high quality construction and was packaged well. Installation was easy and saved me a lot of $ vs. having my dealer install an OEM filter.

Good Fit
I don’t expect this filter to last as long as the original filter but that’s okay because it is about half the cost. It looks well made. I didn’t see any flaws.
I chose this filter because it had some of the fewest complaints regarding the fit and it worked well for my ‘23 Subaru Forester. I may go back to an OEM filter next time but it’s nice to know that this one will work for me.
