The engine air filter sits inside a sealed airbox in the engine bay, upstream of the turbocharger intake.

On the 2019 Mercedes-Benz CLA-Class, the airbox houses the filter to protect the 2.0L inline‑4 turbocharged engine from dust and debris. The cabin air filter, by contrast, is typically positioned behind the glove box in the HVAC intake path. If you prefer, our technicians can access and replace both during one visit.

• Engine: pre‑MAF, pre‑turbo filtration for stable power
• Cabin: dust/pollen media; charcoal options for odor control
• Service each on its own interval per the maintenance guide
