  • Molded rubber intake manifold gasket for a precise intake seal
  • Includes thermostat housing O-ring for related sealing service

Detailed Sealing Construction

Mahle HS54517E is an OEM-standard gasket set engineered around the sealing surfaces involved in cylinder head service. The multi-layered steel head gasket is paired with a perforated steel exhaust manifold gasket and a molded rubber intake manifold gasket to address the major leak points in the upper engine assembly.

Common Problems This Set Addresses

  • Coolant or combustion leakage at the cylinder head sealing surface
  • Intake manifold sealing issues that can affect idle quality and vacuum integrity
  • Exhaust manifold gasket leakage that can create noise or exhaust odor
  • Thermostat housing seepage at the sealing ring
  • Service delays when a complete upper-engine gasket set is needed for reassembly
