An upgrade common among M50/S50US engines is to switch out the headers for M52/S52 manifolds; this requires 2 EGR block-off plates for proper installation. Removing the Secondary Air Pump (SAP) leaves two head ports exposed, which must be sealed. The block-off plates are simple to install, utilizing the existing studs in the head and secured with original nuts. Not for street use.
