K&N 33-2985 Air Filter Product Reviews

Wednesday, November 28, 2018 - Part 33-2985
I use K&N filters in all my vehicles. The increase in power to the Mercedes E350 was immediate. The off the line power and highway passing power is fantastic. Definitely worth the investment.

I have used K&N filters on my previous vehicle, 2012 Audi A4, and never any issues. I now own a 2013 Mercedes C300 Sport 4matic. I love the performance, quality and fit of the K&N filter. There is a noticeable increase in performance and also gas mileage is a nice bonus.

It’s the only filter I would ever put in my vehicles. Period. Don’t play yourself.
