K&N 33-2985 Air Filter Product Reviews

Monday, September 5, 2016 - Part 33-2985
I've had such an improvement with the air filter, I bought for the 2006 SLK350 that I purchased the correct air filter for our 2014 C300 4matic. My only problem is I'm unable to find any installation videos on either the K&N website or You-Tube to walk me through the proper method of installation for the C300. My two options are to delay or have the dealer where I bought the car install it for me. NOT what I had in mind. I attempted the website contact option on the computer but was not successful in getting through. Regardless of my predicament I still think the K&N products are excellent.

The Filter was just great and no problem to replace the old Filter. I did notice the car has more pickup with this new K&N Filter. Regards

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.
