ACCEL's HP copper spark plug fitting your 2011-2019 5.0L Coyote Mustang or F-150 is designed to provide a stronger spark, meaning improved fuel ignition and consistent performance. ACCEL chose to utilize a copper core over platinum or iridium in their spark plugs for maximum conductivity, improved heat transfer, and the ability to gap for your specific application. This spark plug can be used with a stock gap, or adjusted for boost without risking damage to the electrode. This spark plug is also 1 heat range colder than stock, helping to reduce misfires, pre-ignition, or spark knock during extreme, high-heat conditions often seen in higher horsepower forced induction engines.
