K&N BMW 3 Series Performance Intake Kit

The K&N 99-05 BMW 3 Series Performance Intake Kit is engineered to enhance your engine's performance by increasing the volume of airflow. The system is paired with K&N's signature washable and reusable High-Flow Air Filter, which uses oiled cotton filter media. This oversized, conical filter allows for extended service intervals, up to 100,000 miles under normal highway driving conditions. Included in the kit is a custom-designed heat shield, crucial for preventing the intake air from absorbing excessive heat from the engine bay, thereby maintaining optimal air density for combustion. The entire system is designed for a straightforward installation, typically completed within 90 minutes. This intake system is compatible with various BMW 3 Series models from 1999 to 2005, including the 323Ci, 323i, 325Ci, 325i, 325xi, 328Ci, and 328i. It is important to note that some K&N intake systems are not street-legal for use on pollution-controlled motor vehicles in California. Consumers should verify the CARB status for specific vehicle applications.
