Cometic Peugeot XU9J4/XU9J4Z/XU10J2/XU10J4 .036in MLS Cylinder Head Gasket - 86.5mm Bore - C4227-036

The Cometic Peugeot XU9J4/XU9J4Z/XU10J2/XU10J4 .036in MLS Cylinder Head Gasket - 86.5mm Bore - C4227-036 is a precision-engineered head gasket with a 86.5mm bore and .036" 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.
