Mahle 54465 Engine Cylinder Head Gasket

Mahle 54465 Cylinder Head Gasket

The Mahle 54465 engine cylinder head gasket is an OEM-standard sealing component built for reliable combustion chamber sealing and consistent compression retention. It uses composite construction with a graphite cylinder head gasket material and a 0.06 in. (1.57 mm) thickness for applications that call for this specification.

Compatible with Subaru applications that reference part number 11044 AA243, this gasket is a direct-fit sealing solution for engine rebuild and head service work. Mahle gaskets are trusted by OEMs and technicians for precise sealing performance in demanding engine environments.

Detailed Description

Mahle 54465 is engineered as an OEM-standard cylinder head gasket for engines that require a composite, graphite-faced sealing design. The gasket’s thickness and bore diameter are important dimensions for maintaining proper sealing around the combustion chamber, coolant passages, and oil passages during cylinder head service. For Subaru engine repair work, the 54465 part number is a relevant reference when matching the original sealing specification.

This part cross-references Subaru 11044 AA243 and FEL-PRO 26581 PT for the same application. When replacing a Subaru head gasket, matching the correct bore size and thickness is critical to restoring sealing integrity after head removal, overheating repair, or top-end engine service.

What This Head Gasket Helps Address

• Compression loss from a failed cylinder head seal
• Coolant leakage between the head and block
• Oil seepage at the head-to-block interface
• Combustion gas leakage into cooling passages
• Sealing issues after cylinder head resurfacing or engine teardown

Installation Notes and Tips

Verify the engine’s required bore diameter and gasket thickness before installation. Clean and inspect the cylinder head and block mating surfaces, and confirm that the head is within service specifications before assembly. Follow the vehicle manufacturer’s torque sequence and torque-angle procedure, and do not apply sealant unless the engine service procedure specifically calls for it.

For Subaru head gasket service, confirm the original part number and engine code before ordering. The Mahle 54465 should be matched to the exact application to ensure proper sealing performance.
