CENCAL B46/B48 BMW Charge Pipe Kit (F&G Chassis)

Upgrade from your factory plastic charge pipe to the Cen-Cal B46/B48 Aluminum Charge Pipe for maximum airflow, reliability, and long-term performance. The OEM charge pipe on B46 and B48-powered BMW and Supra models is made from plastic—an inherent weak point that can crack or fail under increased boost pressure. Our upgraded aluminum version eliminates that concern entirely, offering both improved durability and enhanced throttle response.

Precision-engineered from high-quality aluminum, this charge pipe provides superior airflow and structural strengthwhile maintaining OEM fitment and compatibility with factory couplers and sensors. Whether your vehicle is stock or tuned, this upgrade is a must-have for reliability and performance peace of mind.

Each charge pipe includes a pre-welded methanol injection bung, sealed for those not using meth injection. Designed for both daily drivers and track builds, this charge pipe ensures consistent boost delivery and dependable performance in any condition.
