Excellent product. I have replaced OEM filters with these for many years. See the difference in performance and fuel economy. Worth the investment for my ML350.

Great filter. I have used these filters for years on all out Mercedes products from the SUV to the roadster and we see increased fuel economy and performance with these filters. Well worth the cost and the quality is unmatched to any filter on the market.

What can you say, it's a K&N air filter. They don't make them any better. Noticed a big change in the power of my Benz. Easy to install and a great price. All my vehicles use K&N.

Didn't notice much of a gain in my 2013 e class, however this is a K&N so I KNOW this is the best..... and no more dealer raking me for a replacement.

This is a perfect fit inside the air box and took me 15 minutes to install (I was going slow). I have been a K&N user for the past 15 years and I never once had a single problem with the air filter. Every car I have owned has a filter in it and I do notice the engine is more responsive and that the air flow is less restrictive.
