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.
