Great. More acceleration. Love them.
Wes, Kentucky
Ordering directly from K&N was easy and the most cost effective. Filters fit perfectly in my C300. They were head and shoulders better quality than even OEM filters.
Russ Maxson, Budd Lake, New Jersey
Have been a K&N user for 40 years and use their products in both my street cars and my race cars. Simple, guaranteed to fit right and economical since they are cleanable and resuable. Can always count on them for some extra fuel milage gains too once the ECU has time to update itself.
