Description
Refresh and upgrade your ignition system with the APR Ignition Coil & Spark Plug Kit for 4.0T EA825 8-cylinder engines. This kit combines high-output APR ignition coils with APR Iridium Pro spark plugs, engineered to work together for a stronger, more consistent spark. Designed to enhance throttle response, smoother idle, and reliable performance under heat and load, this kit is ideal for stock and high-performance tuned vehicles.
All components are direct-fit and plug-and-play, requiring no wiring, coding, or tuning changes. Coils are batch-tested for reliability, while iridium spark plugs ensure stable combustion and high-temp durability under demanding conditions.
