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. 🙄

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.

Good quality, but could fit more snug in filter compartment.
Color: CA12061
Appears to be good quality material. It fits the model of car I bought it for, 2016 Honda Pilot, however it does not fit as snug as the other filter did. The dimensions could be improved a little, but I don't believe there is a gap along the end to allow anything to get by.

Durable air filter
Color: CA12061
Great reviews so I purchased this for my 21 Acura TLX. This was the first time I changed the filter on my car. Very durable and thick, so far so good. It was super easy to install, don’t see much of a change in fuel usage but that wasn’t a concern. Great value for money will buy again.
