The DO88 Charge Pipe for vehicles fitted with 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, as well as the Toyota GR Supra A90 with a water-cooled Intercooler.
The Charge Pipe utilises mandrel-bent aluminium tubes, CNC-machined fittings and a specially developed silicone coupling hose with three flexible segments. This construction is designed to accommodate thermal expansion and contraction without placing stress on the connections. The tubes are finished with a black powder coating and fit without interfering with the engine cover.
