The Cometic head gasket for Mitsubishi Lancer Evolution models 4–9 is specified for an 87.5mm bore and 0.059 inch thickness and is engineered to seal while requiring less clamp load. Its design promotes even load distribution across the sealing area, reduces bore distortion and does not require sealants or repeated re-torque. Use this gasket as a direct-fit replacement for supported Evo 4–9 engines where the listed bore and thickness match the application.
