The do88 Charge pipe for vehicles 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-models and is designed to improve both durability and airflow.
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 accommodates thermal expansion and contraction without causing stress on the connections. The tubes feature a black powder coating and maintain full compatibility with the original engine cover.
