Cometic C4293-051 MLS Cylinder Head Gasket for BMW M10B18/M10B20 90mm Bore .051 Inch

The Cometic C4293-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for BMW M10B18 and M10B20 engines. This gasket features a 90mm bore and .051 inch (1.3mm) compressed thickness, making it ideal for both stock rebuilds and performance applications.

Multi-Layer Steel Construction:

MLS gaskets provide maximum sealing performance for high output engines and require no sealants. These gaskets have increased strength because they are comprised of multiple layers of stainless steel, which also creates the ability to rebound and resist corrosion.

Advanced Viton Coating:

The outer layers are embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material that is heat resistant to 250°C (482°F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes.

Versatile Material Compatibility:

MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks, and can withstand the shearing force created by the two materials.

This gasket is designed for BMW M10B18 1.8L and M10B20 2.0L SOHC 8-valve engines commonly found in classic BMW 2002, E21, and E30 318i models from the 1970s and 1980s.
