The do88 Charge pipe for vehicles with the BMW B48 and B46 engines has been developed as a durable and performance-oriented replacement for the original plastic charge pipes. This kit is suitable for various BMW F-series and G-series models and for the Toyota GR Supra A90 with a water-cooled intercooler.
The charge pipe makes use of mandrel bent aluminum tubes, CNC-machined connections and a specially developed silicone coupling hose with three flexible segments. This construction is designed to accommodate thermal expansion and contraction without causing stress on the connections. The tubes are finished with a black powder coating and connect without interference with the motor cover.
