Mercedes Benz CLK350 Air Filter

Common Issues with the Mercedes Benz CLK350 Air Filter

Your Mercedes Benz CLK350 is one stylish vehicle that's been built for maximum comfort and convenience. Nice to look at and easy to drive, you wouldn't ask for more when it comes to this ride. But all that class and features won't mean much if you've got problems with its air filter. Once this filter goes bad, then expect to experience rough engine noises, lower fuel mileage, and higher emissions from your vehicle. Learn to identify symptoms of a bad Mercedes Benz CLK350 air filter so you could replace it at once, before it affects your car's performance in the long run.

Poor mileage

Lower fuel efficiency is a sign that you might have a clogged air filter, which in turn is affecting how your engine burns up fuel. Your vehicle's engine relies on a proper fuel to air ratio to effectively burn fuel and power up your car. If you have a clogged air filter, then your engine might not be receiving enough air to properly combust fuel. Depending on the air filter that you have installed, you can either wash it if you have a metal filter or simply replace it if it's made from paper or some other disposable material.

Black smoke exhaust

Again, another symptom of a bad air filter is black smoke from your exhaust. If the air filter is clogged, your engine will use more fuel to run, which in turn can lead to a "rich" mixture that leads to a blacker exhaust.

Rough noise coming from the engine

Because of the lack of air coming in through a dirty filter, even your engine's spark plugs could get affected. A broken air filter might allow dirt and debris to enter, which in turn can clog your spark plugs. Replacing the air filter and cleaning or even replacing your spark plugs should solve the problem.

Other tips

Most mechanics would advise drivers to simply replace their air filter, whether they're dirty or not, every 12,000 to 15,000 miles to ensure that they don't break or clog up. It's pretty simple to replace an air filter on your own and the added pre-emptive care will make sure that your Mercedes Benz CLK350 will run smoothly for a longer time.

  • Tips on Maintaining your Mercedes Benz CLK350 Air Filter 27 February 2013

    A clean engine will undoubtedly perform better, use fuel much more efficiently, and would generally last for a longer time. So to keep your Mercedes Benz CLK350's engine running at its best, then you have to take care of your air filter. Air filter maintenance is probably one of the easiest tasks that anyone can perform. Technically, you don't maintain an air filter since you simply take out your old one and slip in a replacement. But if you opted for a reusable one, then you can simply wash them from time to time. Regardless of the type of air filter in your car, you'd also want to clean a few parts in your vehicle's air intake to get rid of dust and grime.


    Most folks would probably have a disposable air filter in their CLK350 and it's highly recommended that you replace this filter once every 12-months or 12,000 miles, whichever comes first. You might have to replace it even sooner if you live a dusty place, so it's best to inspect your air filter every quarter to see if it's too clogged up for use already.


    Even before you reach the air filter's life cycle, you'd want to take a look at it once in a while to see if anything is stuck in it that could disrupt air flow. Simply take the air filter out and gently tap it to get rid of any stuck debris.


    If you are using a reusable air filter, then you wash it from time to time. Most reusable filters can simply be washed in running water. Other brands have special solutions that come with the filters, so you should follow the brand's instructions on how to clean them properly. With proper maintenance and regular cleaning, these reusable filters should last the lifetime of your CLK350. Make sure that you let them dry completely before you install them back into your vehicle.


    While you're cleaning or replacing your Mercedes Benz CLK350 air filter, do take the time to wipe the air intake and other areas near the air filter. Grime and dust could build up in these areas, so a quick wipe with a damp rag should do.
