Fits Great!
Size: 8.8" x 9.3" x 1.2"
Have a 2014 Honda Pilot and this cabin air filter fit perfectly and was extremely easy to install. Got dirt cheap during a lightning deal! What can I say- 5 stars and just buy it!

Works great
Size: 8.8" x 9.3" x 1.2"
This fit perfectly in my 2017 Acura MDX. I can change my own filter in less than 5 minutes and it costs much less than the OEM. The filters lasted me about a year before I needed a new one.

Great product !!!
Size: 8.8" x 9.3" x 1.2"
The product was in great shape when delivered. Even though the package was thin as it is the delivery was made with card and all was well with product. The instructions were good to use and change in my car. Also it showed the make of vehicle so I won’t be confused at all. Overall it was a great buy
