The DO88 Charge Pipe for vehicles fitted with the BMW B58 Gen 1 engine 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, G-series and X-series models and is designed to improve both durability and airflow.
The Charge Pipe utilises mandrel-bent aluminium tubes, CNC-machined fittings and a specially developed silicone coupling hose comprising three flexible segments. This construction accommodates thermal expansion and contraction without placing stress on the joints. The tubes feature a black powder coating and remain fully compatible with the original engine cover.
