Description
HIGH PERFORMANCE SPARK PLUGS. The Accel HP Copper Spark Plugs with Stock Heat Range are engineered to deliver a stronger spark and superior combustion performance, especially under the high-pressure conditions found in performance engines. Suitable for both street and strip use, these plugs improve ignition efficiency and reduce misfires by effectively dissipating heat and optimizing spark exposure.
_x000D__x000D_CONSTRUCTION AND APPEARANCE. Featuring a copper core, these plugs provide enhanced thermal conductivity compared to iridium or platinum options. The machine rolled threads ensure precise thread engagement and consistent torque retention, while the "C"-Cut design exposes the spark kernel to improve burn efficiency. Equipped with a resistor and a projected tip with a tapered seat, these plugs maintain a standard appearance suitable for OEM-like installation.
_x000D__x000D_INSTALLATION. Installation is straightforward and requires no drilling or modifications. Their stock heat range and standard length make these plugs compatible with factory specifications. Proper torque can be applied using conventional tools within the recommended 7.2 to 14.5 lb.ft. range.
_x000D__x000D_APPLICATION. Designed to fit the 2015 to 2019 Ford Mustang equipped with the EcoBoost 3.5L V6 engine, these spark plugs offer reliable, direct replacement performance without modifications.
