High-voltage ignition coil, compatible with STIHL MS661 and MS661C lawnmowers--BIEMMEDUE

This product was specifically developed for the STIHL professional high-performance chainsaws MS661 and MS661C. It meets the original factory specifications of the series. High-voltage transformer (ignition coil/ignition module): This component is the heart of the engine's electronic ignition system. Using CDI (capacitor ignition) technology, it precisely converts the magneto ignition pulses into high-energy electrical sparks that ignite the fuel-air mixture in the cylinder via the spark plugs. Manufactured to the highest performance standards of automotive manufacturers (OEMs), it is an ideal replacement for original parts. It offers highly effective solutions for critical faults in high-end chainsaws caused by aging or damaged ignition coils, such as starting difficulties, rough idling, misfires at high speeds, power loss, and sporadic stalling. This powerhouse ensures reliable, powerful and precise ignition under a wide range of extreme conditions.
