The Cometic MLS head gasket for the BMW M54 is a multi-layer steel gasket for engine builders who want a stronger, more durable head seal than the standard gasket. It suits both naturally aspirated and boosted builds.

Key features

• Multi-layer steel (MLS) construction with embossed outer layers and an active combustion seal on multiple layers.
• Built for high cylinder pressures, with stronger sealing than a standard factory gasket.
• Multiple thicknesses available, so you can set your compression ratio and piston-to-head clearance.
• Cometic quality, a trusted name for performance and race engine gaskets.

Fitment

Fits the BMW M54 engine in both M54B25 and M54B30 versions. Bore size is 85mm.

Choosing your thickness

Choose your gasket thickness from the Thickness drop-down above. Thickness changes compression ratio and piston-to-head clearance, so check it against your engine build before ordering.
