HARD Motorsport M52/S52 EGR Block-off Plates - BMW E36 M3
Our EGR Delete Plates block the EGR ports on OBDII E36 headers. These are necessary if you remove the secondary air pump (SAP) or upgrade your OBDI car with OBDII headers.
The perfect solution for track builds. These can also be used when installing S52 headers on an M54 E46.
Optional gaskets available, if you don't already have your own. They come in pairs (recommended).
