Product Description


Generators Spark Plug for GS420 /J 312 replace P3.V3 347257 and P3.V5 401824


Elevated temperatures have been observed in the combustion chambers of engines under certain operating conditions. This can cause the temperatures at the spark plug electrodes to become too high. To increase the service life of the spark plugs, noble metals are applied to the centre and earth electrodes. If thermal conditions are too hot these metals can melt, which adversely affects the service life of the spark plug. This can result in short-circuits at the electrodes (globule formation) and reduced spark-plug voltage. TAKUMI spark plugs drastically reduces the risk of so-called globule formation.
