What heat range spark plug should I use?
The optimal firing end temperature is approximately 500°C (932°F) to 800°C (1472°F). The two most common causes of spark plug problems are carbon fouling (< 450°C) and overheating (> 800°C).
How much heat does a spark plug produce?
The operating temperature of a spark plug is the actual physical temperature at the tip of the spark plug within the running engine, normally between 500 and 800 °C (932 and 1,472 °F).
How do I know if my spark plug has a heat range?
The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.
Do I need a hotter or colder spark plug?
When making spark plug heat range changes, it is better to err on the side of too cold a plug. Running too cold a plug can only cause it to foul out, whereas running too hot a plug can cause severe engine damage.
Does spark plug heat range affect performance?
Choosing the right heat range is crucial for high performance engines. If the heat range is too cold, the spark plug will be unable to properly self-clean by burning off carbon deposits. If it the heat range is too hot, your engine could experience detonation, pre-ignition, or power loss.
Do Iridium plugs burn hotter?
Denso Iridium Power plugs feature the heat range at the end of the part number. Denso plugs get colder the higher the number, hotter the lower the number. Starting with part # IK20 (heat range 20), a colder plug would be # IK22, a hotter plug would be # IK16.
Which NGK spark plug is the best?
Iridium IX Spark
NGK 6619 Iridium IX Spark Plugs snagged the top pick in our spark plug comparison because they offered the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
What happens if I use a hotter spark plug?
If the tip temperature is higher than 1560°F, the spark plug will overheat which may cause the ceramic around the center electrode to blister and the electrodes to melt. This may lead to pre-ignition/detonation and expensive engine damage.
Why would you run a hotter spark plug?
A “hot” spark plug has a longer insulator that prevents heat transfer into the water jackets. It keeps more heat in the tip of the spark plug, which helps burn off combustion chamber deposits. But if there’s too much retained heat, the engine will experience preignition.
What does the heat range of a spark plug mean?
The heat range of a spark plug is the range in which the plug works well thermally . The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.
Why run colder spark plugs?
So for the basics of how colder plugs work: A “colder” plug is litterally a spark plug with a smaller pedestal. The reason it is called a colder plug is that it will cool off between combustion cycles faster than a plug with a larger pedestal. Since the plug is able to cool off between combustion cycles there is less heat in…
