Good deal
Size: CF10930&16546AA090
Seems a bit thinner than my last two, but they did come together for the price of one. Seems to be of good quality non the less. Fits well in my 2014 Subaru forester

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!
Color: CA12061
My mechanic says this is a great filter. They installed free (30 seconds) whereas Honda wanted $150 plus labor is it to install theirs. 🙄
