Our EGR 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.
These may be welded in place, or simply use the exsisting hardware.
FOR TRACK USE ONLY
