The Rogue Engineering EGR Blockoff Plate (Exhaust Air Valve) blocks off the port on all S54, S50B32 Euro and M54 engines for off road use. This does not fit S50B30 Euro engines.
CNC'd from 6061 Aluminum, this is intended for track use only. It does require ECU software to be modified to remove the "air pump" faults when used with a stock ECU.
