Detailed Description

Mahle HS54686 is an engine cylinder head gasket set intended for repair work on compatible BMW 540i, BMW 740i, BMW 740iL, BMW X5, BMW Z8, and Land Rover Range Rover applications. The set focuses on the supporting gaskets and seals needed during top-end engine service, with a composite exhaust manifold gasket and molded rubber intake manifold gasket included in the package contents. Because the head gasket and cylinder head bolts are not included, this part number is best matched to jobs where those components are sourced separately. This part cross-references Land Rover (e.g., N/I) for the same application. Mahle HS54686 is listed for 1998-2005 BMW and Land Rover coverage, including 1998 BMW 540i and 740i applications noted from 09/98.

What It Is Used For

• Replacing worn sealing components during cylinder head service
• Addressing coolant or oil seepage at engine sealing surfaces
• Restoring intake and exhaust manifold sealing integrity
• Supporting repairs where torque-to-yield fastener replacement is required

Confirm engine code, production date, and gasket layout before ordering. Fitment notes specify that the head gasket is not included, cylinder head bolts are not included, and cylinder head bolt replacement is recommended.
