I have been using K&N filters on all my Autos and Bikes for the last 44 years. Every one of their products have been flawless. I even feel a sense of loss when a vehicle gets sold with the filter still in it And now there are cabin air filters available too. K&N do their research and deliver a great product as the industry changes. That's what I call super customer care. Ken New York

Excellent filter fits perfectly in my new 2018 Honda CRV. I have used these filters on every new car I buy and they are great, well worth the money.
