Since installing the air filters I have noticed better gas mileage and a slight increase in power. They were easy to install and come with stickers stating they are lifetime filters so no one replaces them by mistake!

We always change out the OEM air filter for a K&N air filter. These (2) filters fit perfectly, a bit of a chore to replace, but well worth the peace of mind knowing our MB engine is getting the smooth, clean air flow it requires to run at peak performance. Highly recommend!

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.
