K&N 57 Series FIPK cold air intake system for the naturally-aspirated Porsche 911 (996 chassis). A high-density polyethylene (HDPE) rotationally-molded intake tube increases airflow volume to the engine, paired with a washable, reusable oiled cotton High-Flow Air Filter in K&N's oversized conical design (up to 100,000 miles between filter services under normal driving). A custom heat shield protects intake air from engine bay heat. Typical install time is under 60 minutes.
