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.

Game changer for my truck
Size: 1.9" x 9.9" x 11.4"
I installed this K&N Lifetime Cabin Air Filter in my 2016 F-150 and noticed the difference right away. The airflow is stronger, and the cabin smells fresher even when driving through dusty or humid areas. What I really like is that it’s washable and reusable—so I won’t have to keep buying filters every year.
Fitment was perfect and install took under 10 minutes. Just pop out the old one, slide this one in, and you’re good to go. It feels solid and well made, not like those cheap paper ones. It’s definitely worth the investment, especially if you drive a lot or have allergies.
Highly recommend for anyone with a Ford or Lincoln vehicle—it pays for itself quickly!
