DO88 Charge Pipe Kit BMW F-series M140i/M240i/340i/440i B58 etc.

The do88 Charge pipe for vehicles with the BMW B58 Gen 1 engine has been developed as a durable, performance-focused 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 uses mandrel-bent aluminum tubing, CNC-machined connections, and a specially developed silicone coupler hose with three flexible sections. This construction accommodates thermal expansion and contraction without placing stress on the connections. The tubes feature a black powder coating and remain fully compatible with the original engine cover.
