The Evolution Racewerks Diverter Valve Charge Pipe Kit is engineered for the BMW Z4 sDrive35i/s N54 Twin Turbo engine (2009–2016). Designed to replace the OEM diverter valve pipe, it eliminates boost leaks, improves airflow, and ensures maximum throttle response and reduced turbo lag.

Manufactured in-house in the USA, the charge pipe is constructed from lightweight 6061 aluminum and features precision CNC-machined factory-style o-ring throttle body and MAP sensor flanges. This design replicates the OEM connection for a leak-free, plug-and-play installation. Beaded ends with T-bolt clamps prevent the intercooler piping from separating under boost. The factory diverter valve sound baffle is removed to optimize airflow.

Optional Type III Hard Black Anodizing improves durability and gives a stealthy OEM appearance. The pipe is also available in brushed or mirror polish finishes, with custom anodizing colors available as special orders.
