BMW Air Filter - Genuine BMW 13718091495

Product Information

The engine air filter is a critical component of the intake system, allowing clean, fresh air to enter the combustion chamber while preventing dust, dirt, and other contaminants from reaching the engine. Located within the air intake box, it traps particles as air flows through, ensuring optimal engine performance, improved fuel efficiency, and reduced emissions.

Common failure symptoms:
Clogging: Accumulated dirt and debris can restrict airflow, leading to reduced performance, poor fuel economy, and increased emissions.
Moisture contamination: Exposure to water or excessive humidity can saturate the filter, restricting airflow and potentially damaging engine components over time.
Age-related wear: Filter materials can degrade and become brittle, reducing filtration efficiency and increasing the risk of tearing.
Decreased fuel efficiency: Restricted airflow forces the engine to compensate with more fuel, lowering efficiency and overall performance.
Misfires or hesitation: Insufficient airflow can result in incomplete combustion, causing engine hesitation or weak power delivery under load.

It is recommended to inspect and replace the engine air filter every 24,000 – 48,000 km (15,000 – 30,000 miles), depending on driving conditions.
