    Perfect Fit for 2021 Honda Odyssey Elite
    Color: CA12061
    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.

    Great quality and cost effective!

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

    Top Shelf Quality!
    Color: CA12061
    This is superior to the OEM filter the Ridgeline comes with and at a significantly lower price than Honda will charge you for the replacement. This arrived promptly, packaged securely, fit precisely and by the time I'm getting around to this review, I've already driven 6-7,000 miles and I recently checked it out- perfect! I usually change these out around 7-8,000 miles and this filter is doing exactly what it's supposed to do and frankly, I think it will easily go 15,000 miles before needing replacement. IMHO, this is far superior to the Honda OEM air filter. This is a great filter and you won't be disappointed.
