Engine sealing set for Mitsubishi applications

The Mahle HS54143 engine cylinder head gasket set is built for Mitsubishi Diamante, Montero Sport, and Montero applications that require OEM-standard sealing components. It combines multi-layer steel head and exhaust manifold gaskets with a molded rubber intake manifold gasket for a precise sealing solution.

Key features

  • Multi-layer steel cylinder head gasket for durable sealing performance
  • Multi-layer steel exhaust manifold gasket for high-temperature sealing areas
  • Molded rubber intake manifold gasket for intake sealing surfaces
  • OEM standard grade for factory-style service replacement
  • Contains miscellaneous gaskets and seals for related sealing points

Detailed description

Mahle HS54143 is an engine cylinder head gasket set for Mitsubishi Diamante, Mitsubishi Montero Sport, and Mitsubishi Montero models listed in the fitment data. The set is built around multi-layer steel construction for the cylinder head gasket and exhaust manifold gasket, while the intake manifold gasket uses molded rubber for the specified sealing interface. This part number, HS54143, is intended for service work where the original sealing surfaces need an OEM-standard replacement. This part cross-references FEL-PRO (e.g., HS 26193 PT, HS 26193 PT-1) for the same application.

What this part helps address

  • Coolant or compression loss at the cylinder head sealing surface
  • Exhaust leakage at the manifold sealing area
  • Intake manifold sealing issues
  • Sealing wear during cylinder head service
  • Torque-to-yield fastener service requirements

Installation notes and tips

Fitment includes Mitsubishi Diamante, Mitsubishi Montero Sport, and Mitsubishi Montero applications across the listed years. Review the fitment notes before ordering: some applications require cylinder head bolt replacement, and the exhaust manifold gasket is not included for several listed configurations. Use with MS16280 where specified in the fitment notes. The part number HS54143 should be matched to the exact engine and emissions configuration shown in the vehicle listing.

Quality assurance

Mahle gaskets are trusted by OEMs and technicians worldwide for sealing applications. HS54143 is an OEM-standard gasket set built to meet service-replacement expectations for Mitsubishi engine repair.
