Always love K&N filters. Always fit, always improve, whats not to like?
Linda, Texas
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!

Been using your products for many years. Never have a problem. Clean and oil the filters as needed. Everything is great!
