The BorgWarner EFR block-off plate is a simple service plate intended for EFR recirculation valve locations. It functions as a block-off solution to close the recirculation port when required by a specific installation or modification. Use this plate when a sealed recirculation opening is needed during turbo servicing or system changes on EFR-family chargers.
