Mercedes-Benz CLS Class Performance Air Intake - K&N Engineering - Drop-in High-Flow - `09-`14. This drop-in high-flow air filter restores and improves intake airflow using K&N's washable, reusable oiled cotton media and installs into the factory air box for a simple upgrade.
Designed for enthusiasts who want better breathing from their 2009–2014 CLS models, this K&N replacement filter captures contaminants while allowing increased airflow compared with disposable paper elements. The layered, oiled cotton construction is serviceable and reusable, reducing waste from single-use filters. The filter is a straightforward direct-fit replacement—no modification to the factory air box is required—but always confirm fitment for your specific engine and year before purchasing.

- Washable, reusable layered oiled cotton media for long service life
- Drop-in design fits the factory air box for easy installation
- Engine protection while allowing improved airflow
- Reduces disposable filter waste by being reusable
