The Cometic copper cylinder head gasket is made for 1996–2005 Mitsubishi Lancer Evolution 4G63T engines with an 87mm bore and .043" thickness. The gasket is described as requiring less clamp load, distributing clamp forces evenly across the sealing area, and reducing bore distortion. It claims no need for sealants or re‑torque and is intended for high‑stress turbocharged engine applications where reliable sealing matters.
