DO88 Charge Pipe BMW G-Series B58 M40i/M240i/M340i/M440i etc.

The do88 Charge pipe has been developed for various BMW G-Series models with the B58 Gen 2 engine. This upgrade replaces the original charge pipe and is designed with larger diameters, mandrel-bent tubing, and a reinforced silicone connection for improved durability and airflow.

The system consists of black powder-coated aluminum tubes measuring 60 mm and 76 mm, combined with a specially developed triple-bulged silicone hose reinforced with aramid fibers and stainless steel rings. The charge pipe features CNC-machined connections and is supplied with all necessary mounting hardware and installation instructions.
