Really filters the cabin air
Size: 1.9" x 9.9" x 11.4"
K&N filters are always a cut above. Can’t say the same for service/support after the sale.

Nice air filter
Replaced my K&N filter with this KAX filter. Same performance and better mileage.

A Great Filter (Installed on a 2014 Acura RDX)
I installed this on a 2015 Acura RDX and it has been a fine replacement for the original air filter. The filter offers a good value and resembles the filter that it replaced and seems to be an equivalent replacement in every way. It fit into the housing perfectly and was just as easy to replace as the original filter was. The white color of the filter also makes it easy to see if an excess of dirt has built up on the filter. I'd recommend this filter. The materials are good, it offers equivalent functionality, and great value for the money.

Excellent quality and price
The picture above is of two different brand engine air filters. One is a Fram Extra Guard and the other is the KAX filter, which costs half as much. Can you tell which one is the cheaper KAX filter? There may be a difference in material that is not visible, but they feel and look the same. It seems like a safe bet to try out the KAX and see how well it performs/lasts.
