The 1992 Chevrolet Camaro Z28 as equipped with the 5.7L (350 cid) engine's spark plug gap is dependent on street versus racing use and the plug material. Modern replacement plugs are all pre-gapped from the factory for this application. Budget AC Delco part #R45TS copper is set at .035-inches. Mid-grade AC Delco Professional Platinum #2 is .045-inches. Premium Denso Iridium Power #5303 is .044-inches.
