Dinan High Flow Drop-In Replacement Air Filter BMW

The Dinan High Flow Drop-In Replacement Air Filter line is a direct upgrade for your factory air filter (engine air filter). It lets you keep the stock air box and still get better airflow. A less restrictive filter means the engine doesn't have to work as hard to make the same power, or more. That supports performance and efficiency without a full intake system swap.

Key Features:

• Less restrictive and better flowing than the stock paper element
• Drop-in design that replaces the factory filter and uses the stock air box
• Proprietary oiled cotton gauze filtration media
• Washable and reusable, which lowers long-term maintenance costs
• Quick and easy installation, with no modifications needed
• Available in application-specific configurations for a range of BMW engines and air boxes
