BMW B46 & B48 Spool Aluminum Charge Pipe Kit

The Spool aluminum charge pipe for BMW B46 and B48 engines replaces the weak factory plastic pipe with a stronger, larger-diameter part.

Why you need it

The factory plastic charge pipe is a known failure point, especially once boost goes up. This direct replacement uses lightweight aluminum with a larger inside diameter for better airflow and secure, leak-resistant connections on stock or modified cars.
