Cometic Porsche 928 83-97 104mm Bore .051 inch MLS Head Gasket Left Side H/G - C5783-051

The Cometic Porsche 928 83-97 104mm Bore .051 inch MLS Head Gasket Left Side H/G - C5783-051 is a precision-engineered head gasket with a 104mm bore and .051" compressed thickness for the Left-Hand Side (LHS).

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.
