K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty
Richard Jackson, Cape Coral, Florida
Great service, quick shipping, took about 30 minutes to install, remember it is on a Mercedes SL550. I am a long distance driver, over 100 miles per day, and a mileage nut. Will let you know what happens with mileage, but throttle response is noticeably quicker, I can hear the engine more when I accelerate. Wish you guys had a cold air intake for this monster...I guess its a very limited market.

This air filter is a solid replacement for the standard MB filters.  The car does have a slightly better response, which coupled with the longevity of the filter's life makes for an excellent product.

I bought replacement air filters for my newly purchased 2011 Mercedes E350. After 200 miles of freeway driving with the stock filters I got 27mpg. With the K&N filters installed and after another 150 miles, I got 29.5mpg and the car feels more responsive at the low end. These are great filters, period.
