Function - Converts battery voltage to a high energy spark delivered to the spark plug, enabling combustion in the cylinder and allowing the petrol engine to run. Key benefits - Higher intensity ignition spark for more reliable combustion - Faster recovery and response leading to improved ignition performance and engine responsiveness Material and construction - Made with a high quality copper core for durable and reliable use Installation and use - Easy to install with no complicated tools required; convenient to use Compatibility - Suitable for petrol engines that use spark plug ignition systems Use scenarios - Replacing a worn ignition coil in an older vehicle to restore reliable ignition, smoother idle, and consistent starting - Upgrading ignition performance in engines requiring a stronger spark for better acceleration or high-load operation - Improving cold-start reliability and overall ignition stability in engines used in challenging weather or high-demand conditions
