MAD BMW B58 2016+ F Chassis M140 M240 340 440 Charge Pipe

MAD BMW B58 F Chassis Charge Pipe

Upgrade the factory charge pipe on your BMW B58 with the MAD BMW F Chassis B58 Charge Pipe, a direct-fit replacement designed to improve durability, airflow, and throttle response on stock and tuned B58-powered BMWs.

The factory plastic charge pipe can become a weak point as boost and performance demands increase. The MAD B58 Charge Pipe replaces the OEM plastic piping with larger-diameter, high-flow tubing designed to provide a stronger and more reliable connection between the turbocharger system and throttle body.

Why Upgrade Your BMW B58 Charge Pipe?

The MAD B58 Charge Pipe features smooth, consistent tubing and a larger diameter to reduce airflow restriction through the charge system. A CNC-machined throttle body connection provides precise fitment and a secure seal, while the upgraded construction eliminates the factory plastic charge pipe from the system.

For modified B58 builds, an integrated water/methanol injection bung provides additional flexibility without requiring modification of the charge pipe.

The kit includes 3-ply silicone couplers, stainless-steel clamps, and the necessary installation hardware for a direct OEM-style replacement.

Finished in black, the MAD charge pipe maintains a clean, understated appearance in the engine bay.
