The Cometic Honda B20A3/B20A5 .030in MLS Cylinder Head Gasket - 83mm Bore - C4566-030 is a precision-engineered head gasket with a 83mm bore and .030" 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.
