Fits Great!

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!

I highly recommend this filter! This filter I had fast shipping and is easily installed. Side by side comparison with OEM Honda filter was amazing. I’ll definitely reorder this filter.

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.
