Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.

I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.

Works Fine, Fits Fine

Size: (Pack of 1)

Seem to work and fit just fine and should be better than a cheap paper filter. They cost more but I change the oil on the 5's and the filter on the 10's so it evens out. Not going more than 10K on the filter. If you are only going to use the filter for 5K miles I would stick with the Toyota factory filter. I use the K&N filters on a 2017 Toyota Sienna and a 2018 Toyota Highlander. Both are V6
