MBS Gen 2 3" B58 Aluminum Charge Pipe - BMW G-Series B58TU / Toyota Supra A90 3.0T

MBS Gen 2 3" B58 Aluminum Charge Pipe – BMW G-Series B58TU / Toyota Supra A90 3.0T

Upgrade your BMW or Toyota Supra's boost system with the MBS Gen 2 3-Inch Aluminum Charge Pipe, engineered specifically for vehicles equipped with the second-generation B58TU engine. Featuring an upgraded oversized 3-inch diameter, this charge pipe provides a larger airflow path compared to the factory charge pipe while delivering improved durability and reliability under increased boost pressure.

Unlike standard replacement charge pipes, the MBS 3" Charge Pipe features a larger-diameter design intended to reduce airflow restrictions and support increased airflow demands on tuned and modified vehicles. Whether you're running factory boost, an ECU tune, or upgraded turbocharger components, this charge pipe is an excellent supporting modification for your B58-powered build.

Manufactured from high-quality mandrel-bent T6061 aluminum, the MBS charge pipe replaces the factory plastic component with a stronger, more durable solution. Finished in a premium black powder coating and equipped with precision-machined connections, it delivers reliable performance with a clean OEM+ appearance.
