Each kit is a direct-fit upgrade designed to support smoother idle, sharper throttle response, and reliable performance under heat and load—whether you’re stock or running higher boost and power upgrades. | ENGINEERED AS A SYSTEM: This package pairs APR high-output ignition coils with APR Iridium Pro spark plugs selected for your 8-cylinder application to deliver a stronger, more consistent spark and a complete ignition refresh in one box. | ENERGY OUTPUTS: APR ignition coils increase energy output by up to 14% over stock to help provide a stronger and more consistent spark. Iridium electrodes require less voltage to fire and support stable combustion as cylinder pressures increase. | A DIRECT-FIT UPGRADE: Direct plug-and-play coil replacement plus direct-fit iridium spark plugs—no wiring, coding, or tuning changes required. Always verify spark plug size, reach, gap, and heat range before installation. | HIGH-TEMP DURABILITY: Coils are engineered with upgraded internal components and batch-tested for reliability. Spark plugs feature an iridium electrode and copper core construction for efficient heat dissipation; heat range 10 is designed to support consistent performance in high-heat and high-load conditions. | COMPATIBILITY: Configured for the engine family listed above using spark plug heat range 10.
