GM Ecotec 2.2L Pro Copper Exhaust Gasket

The GM Ecotec 2.2L Pro Copper Exhaust Gasket is engineered for builders and mechanics who demand reliable sealing on turbocharged and naturally aspirated Ecotec applications. This gasket addresses a critical weak point in the exhaust system—the manifold-to-head interface—where combustion gases and thermal cycling create conditions that destroy inferior gasket materials. Whether you're tuning a street machine, building a weekend warrior, or maintaining fleet vehicles, a quality exhaust gasket is non-negotiable for preventing boost leak, maintaining back-pressure, and avoiding expensive header damage.

SCE Gaskets' pro copper construction combines layers of high-temperature copper with stainless steel and graphite facing, designed to withstand sustained heat cycles exceeding 1,800°F without degradation or blowout. Unlike composite gaskets that crush and lose clamp load, copper gaskets maintain sealing integrity across repeated thermal expansion and contraction, critical for forced-induction builds where manifold temperatures spike during boost events. The gasket's engineered thickness and composition prevent the micro-migration of exhaust gases that plague cheaper alternatives, ensuring consistent compression and preventing header leaks that rob horsepower and trigger check-engine codes.

This gasket fits 2.2L Ecotec engines found in Cavaliers, Cobalts, HHRs, and other GM platforms running stock or modified heads. Installation requires proper fastener torque sequence and clean surface prep—any carbon or corrosion on the sealing surface will compromise the seal. For builders running superchargers, turbochargers, or nitrous systems, the pro copper gasket delivers the thermal resilience and repeated-cycle reliability needed to survive dyno pulls and track duty without failure. Replace during any manifold removal, head work, or exhaust system modification to avoid comebacks and ensure the integrity of your tune.
