Cometic BMW M30/S38B35 84-92 95mm .089 inch MLS Head Gasket M5/M5i/M6 - C4478-089

The Cometic BMW M30/S38B35 84-92 95mm .089 inch MLS Head Gasket M5/M5i/M6 - C4478-089 is a precision-engineered head gasket with a 95mm bore and .089" 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.
