5150 AutoSport Head Gasket & Head Stud Kit, BMW S54
Cut Ring Head Gasket The SCE Cut Ring Head Gasket is a direct replacement for BMW part #11127835918, designed for the S54 inline-six engine. Standard OEM and MLS gaskets can only withstand limited cylinder pressure before leaking, making this gasket ideal for applications exceeding 16+ psi. A failing head gasket can cause overheating, power loss, misfires, or catastrophic engine failure. This gasket is made from high-quality reinforced M0115 material, an asbestos-free, OE-approved composite known for durability. Its AISI 304 stainless steel rings embed into the aluminum head for superior sealing, making it ideal for nitrous or turbo setups exceeding 2 bar boost. Installation Notes: Ensure cylinder head and block surfaces are clean, flat, and debris-free. Align the gasket properly on the engine block. Install the cylinder head and secure head bolts or studs per manufacturer torque specs. Do NOT use additional sealants, as the gasket includes a Viton rubber sealant coating. M
