BMW Air Filter (E60 E85 E86) - Hengst 13717521033

Product Information

This OEM air filter is a direct-fit replacement for your BMW, designed to provide effective filtration while maintaining proper airflow to the engine. It installs easily into the factory airbox with no modifications needed.

The engine air filter cleans incoming air before it reaches the combustion chamber, protecting internal engine components from dirt, dust, and debris. Over time, the filter can become clogged, which reduces airflow and negatively impacts performance, fuel economy, and emissions.

Engine air filter failure symptoms include:

• Clogging: Decreased airflow from dust and debris buildup, leading to poor engine performance and increased emissions.
• Moisture contamination: Saturation from water exposure can restrict airflow and damage the filter material.
• Age: Filter media may degrade or tear over time, reducing filtration efficiency.
• Decreased fuel efficiency: A blocked filter disrupts the air-fuel mixture, forcing the engine to burn more fuel.
• Misfires: Insufficient air intake can cause incomplete combustion and engine hesitation under load.

We recommend inspecting your air filter regularly and replacing it approximately every 48,000 kilometers (30,000 miles), or sooner in dusty driving environments.
