The integrated resistor helps minimize radio frequency interference (RFI) that can affect vehicle electronics. This line combines copper core electrodes with nickel tips and ground electrodes to balance conductivity and durability, making it suitable for a variety of ignition systems.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThe Autolite 5243 spark plug features a copper core center electrode that enhances thermal conductivity and improves spark efficiency. The nickel ground electrode and tip provide resistance to wear and corrosion. Its tapered ground electrode tip and tapered seat ensure a secure fit and consistent spark gap. The long projection ceramic insulator improves heat dissipation and mechanical strength. With a resistance of 4000 ohms, this spark plug effectively suppresses electrical noise, protecting sensitive vehicle electronics.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDesigned for use in Cadillac, Chevrolet, GMC, Oldsmobile, and Pontiac models\u003c\/li\u003e\n\u003cli\u003eCompatible with Chevrolet Silverado 1500, 2500 HD, 3500 HD, Tahoe, Suburban 1500, 2500, 3500 HD\u003c\/li\u003e\n\u003cli\u003eFits GMC Sierra 1500, 2500 HD, 3500 HD, Yukon, Yukon XL 1500, Yukon XL 2500\u003c\/li\u003e\n\u003cli\u003eSuitable for Cadillac Escalade, Escalade ESV, Escalade EXT, CTS\u003c\/li\u003e\n\u003cli\u003eAlso compatible with Chevrolet Camaro, Corvette, Impala, Monte Carlo, and more\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by Autolite 5243 Spark Plug\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngine misfires due to worn or faulty spark plugs\u003c\/li\u003e\n\u003cli\u003eReduced fuel efficiency from inconsistent ignition\u003c\/li\u003e\n\u003cli\u003eDifficulty starting the engine in cold conditions\u003c\/li\u003e\n\u003cli\u003eElectrical interference affecting vehicle electronics\u003c\/li\u003e\n\u003cli\u003ePremature electrode wear impacting spark quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the spark plug gap is set to the specified pre-gap size of 0.044 inches (1.10 mm) before installation.
