Glow plug Monster Truck .18-.46 medium

What glow plug to choose? It is best to give a recommendation to the manufacturer and look into the engine manual, if the recommendation is missing, use a medium candle and then change the candle according to the behavior of the engine. Candles are distinguished by fiber strength, where 1 denotes a warm candle and the highest value, up to 9, is cold. A warm candle has a thinner fiber than a cold candle and is related to use. With a smaller engine volume, a warmer candle is used, while a higher engine volume is used for a higher volume. It is also possible to react to outside temperatures, which can affect use and it is better to use a colder candle in warm weather. If the engine is nitrated fuel, it is necessary to use a cooler candle.
