Upgrade your BMW 3 Series with the K&N 57-1002 Performance Intake Kit, designed to enhance airflow and boost horsepower and torque. This high-quality system features a durable, rotationally-molded HDPE tube that increases volumetric airflow to your engine, resulting in improved engine responsiveness and power output. The oversized, conical, washable, and reusable High-Flow Air Filter uses oiled cotton media, allowing you to go up to 100,000 miles between filter cleanings under normal highway conditions, saving time and maintenance costs. A custom heat shield is included to protect intake air from the high temperatures generated in your engine bay, ensuring optimal air density and performance. The entire installation process can typically be completed in less than 90 minutes, making it a convenient upgrade for enthusiasts and daily drivers alike.
