This engine air filter was a perfect fit for our 2021 Honda Odyssey Elite. Installation was quick and easy, popped right into place with no issues at all. The build quality looks great, and it feels just as solid as the factory filter it replaced. It’s always nice to find a reliable replacement part that fits exactly as it should. We drive a lot of gravel as well and this has held up well to those elements. Great value compared to dealership pricing. Will definitely purchase again when it’s time for the next replacement.

My mechanic says this is a great filter. They installed free (30 seconds) whereas Honda wanted $150 plus labor is it to install theirs. 🙄
