Detailed Description

Mahle GS33464 is an engine cylinder head bolt set engineered for BMW inline-six service applications that require M10x110mm steel head bolts. It fits a broad range of BMW models, including 2001-2006 BMW 325Ci, 330Ci, 2004-2006 BMW X3, 2001-2006 BMW X5, 2001-2005 BMW 325i, 325xi, 330i, 330xi, 525i, and 530i, plus 2003-2005 BMW Z4 and 1999-2002 BMW Z3. Additional coverage includes 2000 BMW 323Ci and 328Ci, 1998-2000 BMW 323i and 328i, 1997-2000 BMW 528i and Z3, 1998-1999 BMW 323is, and 1996-1999 BMW 328is.

This part number, GS33464, is built for direct engine hardware replacement where correct head bolt material, head style, and OE-standard fitment matter. It is also a practical match for BMW cylinder head service where the original fastener specification calls for steel M10x110mm bolts.

What It Helps Address

• Replacing stretched or damaged cylinder head bolts during engine repair
• Restoring proper cylinder head clamping force after head service
• Correcting fastener mismatch on BMW M10x110mm head bolt applications
• Supporting reassembly after head gasket replacement
• Resolving OE-style hardware replacement needs on BMW engine builds

Installation Notes and Tips

Verify engine code, bolt length, and thread specification before installation. Clean the cylinder head and block mating surfaces, inspect threads for damage, and follow the BMW service procedure for tightening sequence and torque stages. Because cylinder head fasteners are critical engine hardware, use the correct tightening pattern and replace any related sealing components as required by the repair.
