The do88 Charge pipe has been developed for various BMW G-Series models with B58 Gen 2 engineThis upgrade replaces the original charge pipe and is designed with larger diameters, mandrel curved tubing and a reinforced silicone connection for improved durability and airflow.
The system consists of black powder-coated aluminium tubes of 60 mm and 76 mm, combined with a specially developed triple-coiled silicone hose reinforced with aramid fibers and stainless steel rings. The charge pipe features CNC-machined connections and comes with all necessary mounting hardware and installation instructions.

Frequently Asked Questions
What are the 1/8 NPT connections for?
The two 1/8 NPT connections can be used for methanol injection or for sensors such as a turbo pressure sensor.
Are sealing plugs included?
Yes, two 1/8 NPT termination plugs are included when the connections are not used.
Does the charge pipe fit with the original hood cover?
Yes, the design does not interfere with the installation of the hood cover.
Are adjustments needed for assembly?
On some vehicles, it may be necessary to grind off the edge of the front panel above the radiators by a few millimeters to create extra space for the do88 charge pipe.
