Description
AEM 21-825DS is an application-specific cold air intake for 2007-2011 BMW 335i 3.0L. It replaces restrictive factory intake components to provide a revised airflow path to the engine.
Technical Highlights
- Washable AEM Dryflow synthetic air filter.
- Oil-free filter media; no filter oil is required after cleaning.
Installation & Compatibility
Confirm engine, trim, sensor arrangement, and the applicable fitment entries before ordering. Install all retained factory connections and check for air leaks before operation. Inspect the filter according to operating conditions; dusty environments and track use can require more frequent service. Emissions eligibility depends on the exact vehicle application; do not assume approval from the intake family name.

Match the engine, trim, and required connections as well as the model year.
