Cometic Gasket BMW S14B20/S14B23 .056in MLS Cylinder Head Gasket - 93.4mm Bore - C4294-056

The Cometic BMW S14B20/S14B23 .056in MLS Cylinder Head Gasket - 93.4mm Bore - C4294-056 is a precision-engineered head gasket with a 93.4mm bore and .056" compressed thickness.

The Cometic Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers that conform to surface irregularities and maintain a positive seal. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
