The COBB hard charge pipe for BMW N55 engines replaces the factory charge pipe with a wrinkle-black finished aluminum pipe to improve reliability and airflow downstream of the turbocharger. It provides a durable, direct-replacement route for boosted air and cleans up the intake plumbing appearance. Intended as an upgraded hard pipe solution where the N55 charge plumbing requires a stronger, lasting part.
