Description

The Burger Motorsports JB4 EWG Add-On Connector Harness is designed for BMW F Series N55 and B58 engines with an electronic wastegate. This harness allows the JB4 tuner to directly control the electronic wastegate, enabling higher boost ceilings for more heavily modified vehicles. It is compatible with popular upgrades like E85 ethanol blends and water meth injection systems.
