Cometic Gasket BMW T16b3/T16b4 Tritec .047in MLS Cylinder Head Gasket - 78.5mm Bore - C4308-047

The Cometic BMW T16b3/T16b4 Tritec .047in MLS Cylinder Head Gasket - 78.5mm Bore - C4308-047 is a precision-engineered head gasket with a 78.5mm bore and .047" 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.
