Solid material ensures corrosion resistance, longer service life, high toughness and break resistance. How it worksThe ignition coil module magnetic igniter stores and emits energy repeatedly at different frequencies according to different engine speed. The ignition coil string trimmer converts the low voltage into thousands of volts for ignition of the high voltage spark plug. Use: replacing the ignition coils directly replaces the old or damaged ones, it is very suitable for repair and replacement. Function: ignition coils can convert low voltage to high voltage. Perfect for flywheel work and give off strong sparks. High performance engine generator lawn mower engine ignition coils provide a spark of higher intensity with faster recovery and response. They can improve combustion efficiency and strengthen electrical performance.
