Once you raise boost the factory hardware is a common cause of head gasket failure and head lift. ARP studs let you torque to a precise, repeatable clamp load so the head stays sealed, making this one of the first upgrades for any reliable turbo 4G63 build.\u003c\/p\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003cp\u003eMitsubishi Lancer Evolution I, II and III (CD9A \/ CE9A), 1992 to 1995. 7-bolt 4G63T 2.0L turbo.
