Cometic Gasket BMW M42B18/M44B19 .095in MLS Cylinder Head Gasket - 85mm Bore

If you're rebuilding the top end of your 1991-1998 BMW 318i, 318is, 318ti, or Z3 with the M42B18 or M44B19 engine, a reliable cylinder head gasket is crucial. This Multi-Layer Steel (MLS) gasket from Cometic is designed to handle the pressures and temperatures of these engines, ensuring a solid seal between your cylinder head and engine block.

Cometic builds this gasket using three to five layers of stainless steel. Stainless steel offers increased strength and is chosen for its ability to rebound and resist corrosion, which is important for long-term sealing performance. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps the gasket conform to the surfaces it seals, even under demanding load conditions and on various surface finishes.

This gasket has an 85mm bore and a thickness of .095 inches, making it a direct fit for the specified BMW models. Ensure your engine block and cylinder head surfaces are clean and properly prepared before installation, following the manufacturer's recommended procedures for optimal performance.
