The Cometic BMW 1990cc 86-92 94.5mm .140 inch MLS Head Gasket S14B20/B23 Engine - C4295-140 is a precision-engineered head gasket with a 94.5mm bore and .140" 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.
