Maintain optimal engine performance and filtration with the Genuine BMW OEM Air Filter (13718480400), designed specifically for BMW models equipped with the B48 2.0-litre turbocharged petrol engine. Manufactured to BMW’s original factory specifications, this air filter ensures precise fitment inside the factory airbox while delivering the correct airflow and filtration performance required by modern turbocharged engines.

OEM Filtration Designed for Modern BMW Engines

The air filter plays a critical role in protecting your engine by preventing dust, debris and contaminants from entering the intake system. Modern turbocharged engines such as the B48 rely on clean airflow to maintain efficiency, performance and long-term reliability.

Using a genuine BMW air filter helps ensure:

• Correct airflow characteristics for the factory intake system

• Effective filtration of harmful contaminants

• Consistent engine performance and efficiency

• Proper operation of the turbocharger and intake system

Unlike some aftermarket filters, genuine BMW filtration media is engineered specifically for the vehicle’s intake design and service intervals.

Direct Replacement for the OEM Air Filter

This filter is a direct replacement panel filter designed to fit perfectly within the factory airbox. Installation is straightforward during routine servicing and requires no modifications.

Replacing the air filter at recommended intervals helps maintain optimal engine breathing and prevents reduced airflow caused by clogged or degraded filtration media.
