Perfect fit, great quality
Fit my Honda CRV with no issues. Pretty easy to install and so much less money than dealer or oil change places

Perfect fit on 2008 Honda CRV LX
This KAX air filter was an excellent fit in a 2008 Honda CRV LX. The construction components of the filter (gasket, frame, and filter) are of good quality. I feel good putting this aftermarket filter in the car for the next 12k-15k miles. I took a picture of this filter next to the filter I replaced for frame/size comparison; it is an exact match. Additionally, the filter was wrapped in sealed plastic, boxed, and came with directions.
