The K&N FIPK cold air intake for 2001–2005 BMW M3 3.2L uses a rotationally molded HDPE intake tube to increase airflow volume and pairs with a washable, reusable oiled cotton High-Flow filter. The oversized conical filter design allows extended service intervals—up to 100,000 miles under normal highway driving—and the system includes a custom heat shield. Typical installation is under 90 minutes; check CARB status for California use.
