2014 Mercedes-Benz SLK-Class Air Filter in Sudbury, MA

It’s in the engine bay inside the airbox on the intake side of the 3.5L V6.

The 2014 Mercedes-Benz SLK-Class (V6, engine code 6VNAG3.5) uses a panel-style engine air filter seated in a sealed airbox ahead of the intake tract. Access typically involves releasing clips or screws and lifting the cover to remove the old element. Take care around the mass airflow (MAF) sensor and ensure the perimeter seal seats evenly. If you’d like a quick, documented install with Genuine Parts, you can schedule service at Mercedes-Benz of Sudbury.

It’s typically mounted behind the glove box in the HVAC intake path.

On many 2014 Mercedes-Benz SLK-Class models, the cabin microfilter sits behind or above the glove box, filtering air before it reaches the vents. Access may require removing trim panels and carefully releasing tabs to avoid damaging finishes. If you prefer a no-fuss replacement and proper panel reinstallation, book a visit in Sudbury and our team will handle the fitment and disposal for you.

The engine filter protects the 3.5L V6 intake, while the cabin filter cleans the air you breathe through the HVAC system.

In the 2014 Mercedes-Benz SLK-Class, the engine air filter prevents dust and debris from entering the combustion air stream, supporting performance and fuel quality. The cabin filter screens pollen and particulates for the passenger compartment. Both are service items but live in different systems and use different media. If you’re unsure which you need, our advisors can check both and recommend the right replacement.

• Engine filter = intake protection for performance and longevity
• Cabin filter = passenger air quality and HVAC airflow
• Different locations, media, and service procedures

Common signs include reduced power, lower fuel economy, rough idle (engine), and weak HVAC airflow or musty odors (cabin).

On the 2014 Mercedes-Benz SLK-Class, a restricted engine filter can limit intake air and skew MAF readings, leading to hesitation and higher fuel use. A saturated cabin filter hampers ventilation and can trap moisture, causing odors. If you notice these symptoms while driving in Sudbury or nearby areas, an inspection can confirm the cause and restore performance and comfort.

• Engine: sluggish acceleration and decreased MPG
• Cabin: reduced vent output and stale smells
• Visual: dark, debris-laden filter media

The engine filter is generally DIY-friendly, while the cabin filter may require trim removal best handled by a technician.
