Cometic Gasket BMW M42B18/M44B19 .086in MLS Cylinder Head Gasket - 86mm Bore

When you're rebuilding the top end of your 1991-1998 BMW 318i, 318is, 318ti, or Z3, a solid cylinder head gasket is crucial for sealing the combustion chamber. This Multi-Layer Steel (MLS) gasket from Cometic is designed specifically for the M42B18 and M44B19 engines, featuring an 86mm bore and a .086-inch thickness.

Cometic builds these gaskets with three to five layers of stainless steel. This material choice offers increased strength and resists corrosion, which is important for longevity in the harsh environment of an engine. The outer layers are embossed and then coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This combination helps ensure a reliable seal under various operating conditions and surface finishes.

This gasket is a direct fit for the specified BMW models, making it a straightforward replacement during an engine overhaul. Ensure your cylinder head and block surfaces are clean and properly prepared before installation, following the manufacturer's recommended procedures.
