Advantage of glow plug 1. Dual coil heater can improve engine performance. By heating the engine to operating temperature faster, dual-coil heaters reduce friction and wear during cold starts. This helps to extend the life of the engine and improve its performance and reliability. Friction and wear during a cold start is when the engine is most likely to be damaged, so by using a dual coil heater, this damage can be reduced and the engine's life can be improved. 2. The double coil heater preheats faster. Because a two-coil heater uses two heating coils, it heats the engine to operating temperature much faster than a conventional single-coil heater. This means that in cold weather conditions, the engine can start faster, reducing wear and fuel consumption when starting up. 3. Dual coil heater can improve fuel efficiency. During a cold start, the engine requires more fuel to reach operating temperature. Since the dual-…
