Sealing Performance and Fitment

MAHLE designs its gaskets for dependable sealing that technicians and OEMs trust. This G26748 gasket uses graphite material to help maintain a tight seal at the EGR connection, where heat and exhaust flow can quickly expose weak or worn sealing surfaces. It is a practical replacement for vehicles such as Chevrolet Camaro, Chevrolet Caprice, and GMC C1500 models, as well as many other GM cars and trucks listed in the fitment data.
