      Comments about K&N Panel Type Cotton Gauze Air Filter:

      Great product .
      I had a lot of trouble getting air filters for my Mercedes Benz , but they had em in this location .
      Buying these saved me 200 buck from the dealer install .
      Very easy install I might add.
      It was a exact fit for my 2007 Mercedes Benz cls550 .
      Even saved a little on the promo code and picked up in store .
      K&n is one of the best and proven air filters on the market .

      Only thing I don't like is after awhile cleaning them and recharging them could be a pain if you don't save your old filters . So save the old ones or have a stock oem while the k&n dry up .
      I've noticed maybe 3 or 4 hp and about 1 -3 mpg .
      Overall great product .
      Thanks .

          I was impressed by the increased power my Mercedes makes with the filter. It breathes better and makes a more of a growling sound. It accelerates quicker. I would recommend the filters to anyone who wants increased power and better gas mileage.

                Comments about K&N Panel Type Cotton Gauze Air Filter:

                K&N air filters have been known to out perform OEM air filters. The filter is very low maintenance and will last the life of your vehicle. I have used K&N air filters on other cars as well. Note, for some cars, the oil that is used on the filter can cause issues with the mass air flow sensor - cleaning of the sensor may be required. As far as any changes in exhaust sound is concerned, you'll only notice a difference at higher RPMs.

                Comments about K&N Panel Type Cotton Gauze Air Filter:

                I was unable to get my air box to seal properly because the K&N filter's rubber gasket has an extra .15 - .20 inch lip. I had to use my Dremel tool to cut this lip off both filters for the air box to close properly.

                    • Q:

                      This filter says that two (2) are required. Do I really have to buy 2 filters for my 2006 Mercedes E-350 sedan with the V-6 engine? Other filters shown do not state that 2 are required. Why are 2 required for this one but not the others.
