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.\u003c\/p\u003e\u003cp\u003eMahle 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.\u003c\/p\u003e\u003ch2\u003eWhat it is used for\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing worn sealing components during cylinder head service\u003c\/li\u003e\n\u003cli\u003eAddressing oil or coolant seepage at gasket interfaces\u003c\/li\u003e\n\u003cli\u003eRestoring intake and exhaust manifold sealing surfaces\u003c\/li\u003e\n\u003cli\u003eSupporting valve stem seal replacement during top-end repair\u003c\/li\u003e\n\u003cli\u003ePreparing the engine for reassembly after head service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes and tips\u003c\/h2\u003e\u003cp\u003eConfirm 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.\u003c\/p\u003e\u003ch2\u003eQuality assurance\u003c\/h2\u003e\u003cp\u003eMahle positions this gasket set as an OEM-standard sealing product.
