Mahle HS54655 Engine Cylinder Head Gasket Set

Mahle HS54655 Head Gasket Set

Mahle HS54655 is an OEM-standard engine cylinder head gasket set built for Subaru applications that require precise sealing at the cylinder head, intake, and exhaust interfaces. It uses multi-layer steel construction for the cylinder head gasket and exhaust manifold gasket, with a molded rubber intake manifold gasket for reliable sealing across critical engine surfaces.

Key Features

• OEM-standard engine cylinder head gasket set for Subaru Legacy, Outback, and B9 Tribeca applications
• Multi-layer steel cylinder head gasket material for durable sealing performance
• Multi-layer steel exhaust manifold gasket material
• Molded rubber intake manifold gasket material
• Torque-to-yield design noted for applications that require replacement fasteners
• Includes miscellaneous gaskets and seals for related sealing points
• Mahle HS54655 cross-references FEL-PRO HS 26534 PT and Subaru 10105 AA790

Detailed Description

Mahle HS54655 is engineered for 2005-2009 Subaru Outback, 2006-2007 Subaru B9 Tribeca, and 2008-2009 Subaru Legacy engine sealing service. This head gasket set is built around multi-layer steel sealing surfaces where cylinder head and exhaust manifold sealing demand consistent clamping and heat resistance, while the molded rubber intake manifold gasket supports intake-side sealing integrity. Mahle supplies gaskets trusted by OEMs and technicians, and this set follows OEM-standard expectations for fit and sealing performance. The part number HS54655 is a direct reference for buyers searching for a Subaru Legacy head gasket set, Subaru Outback cylinder head gasket set, or Subaru B9 Tribeca engine gasket set.

What It Is Used For

• Repairing coolant or compression leaks at the cylinder head sealing surface
• Restoring sealing after cylinder head service or engine teardown
• Addressing exhaust manifold gasket leakage at the head interface
• Replacing worn intake manifold sealing components during top-end engine work
• Supporting Subaru engine reseal jobs where torque-to-yield fastener replacement is recommended

Installation Notes and Tips

Confirm engine code and exact vehicle application before installation. Cylinder head bolts are not included, and replacement is recommended for torque-to-yield applications. Clean all mating surfaces thoroughly, inspect the cylinder head for flatness, and follow the factory torque sequence and angle specifications during assembly. Mahle HS54655 is a fitment-specific Subaru gasket set, so verify the vehicle year and model before ordering.
