ST Trackparts BMW E46 Air filter kit (6-cylinder Non-M / 320i, 323i, 325i, 328i)

Complete Air Filter Kit for BMW E46 320i, 323i, 325i, 328i

This comprehensive air filter kit is engineered specifically for the BMW E46 models 320i, 323i, 325i, and 328i, designed to enhance engine performance through improved airflow. By increasing the volume of air entering the engine, this kit optimizes combustion efficiency, resulting in better throttle response and overall driving dynamics.

A critical component of the kit is the included heatshield, which effectively reduces the temperature of the incoming air. Lower intake air temperatures help minimize the risk of heat soak, thereby preserving engine power and reliability under various operating conditions.

The kit is available with or without the air filter. The recommended filter option is a high-quality K&N filter, renowned for its durability and longevity when maintained according to manufacturer guidelines. It is important to note that fitment assurance is provided only when the K&N filter is included. For users opting to use an alternative filter, compatibility requires a 76mm connection diameter, corresponding to the outside diameter of the air tube.

Kit Contents:

• Heatshield (including mounting brackets and weatherstripping)
• Mounting brackets
• Air tube
• Silicone coupler
• Hose clamps
• Hardware for installation
• K&N filter (optional)

All necessary components for installation are included, ensuring a seamless upgrade process for your BMW E46.

For detailed guidance on installation, refer to the Heatshield Installation Manual.
