I use K&N in all my vehicles.
I love K&N filters. I use them on all of my vehicles. They are expensive but pay off quickly since they will be the last one you will have to replace. I have purchased over 12 of these and every time I get a new vehicle soon as it needs a filter I go right to K&N for the replacement.. Great job K&N. Keep it up.
