Detailed description
Mahle HS54731 is a sealing set for BMW engine repair work where the cylinder head area is being serviced. Fitment includes 2006-2007 BMW 525i, 525xi, 530i, and 530xi; 2006 BMW 325i, 325xi, 330i, and 330xi; and 2006-2007 BMW Z4, with the Z4 listing noted through 9/30/06. The kit notes that the head gasket is not included, while valve stem seals are included, so it is suited to jobs that require related sealing components rather than a complete head gasket replacement.
Mahle states that its gaskets are trusted by OEMs and technicians worldwide, and this part follows that OE-standard approach. This part cross-references BMW 11 12 7 548 921 and FEL-PRO HSU26701 for the same application. The HS54731 part number is useful when matching the correct sealing set for BMW engine service, and HS54731 should be verified against the vehicle’s exact engine configuration before installation.
What it is used for
- Replacing worn sealing components during cylinder head service
- Addressing oil or coolant seepage at gasket interfaces
- Restoring intake and exhaust manifold sealing surfaces
- Supporting valve stem seal replacement during top-end repair
- Preparing the engine for reassembly after head service
Installation notes and tips
Confirm the engine code and production date before ordering, especially for BMW Z4 applications. The fitment notes specify that the head gasket is not included and cylinder head bolts are not included, and they recommend bolt replacement. Because this application is torque-to-yield, follow the factory tightening sequence and torque procedure exactly. Clean all mating surfaces thoroughly before assembly and inspect the cylinder head for flatness.
Quality assurance
Mahle positions this gasket set as an OEM-standard sealing product. The HS54731 part number identifies the correct service kit for the listed BMW applications, and the brand’s OE-focused sealing background supports consistent repair planning.
