If the spark plug has completely fouled, and the engine will not operate correctly, the spark plug may need to be replaced and the fouling cause identified. Some types of fuel additives in lower quality fuels can cause spark plug deposits that can lead to misfires, pre-ignition, etc. The optimal firing end temperature is approximately 500C (932F) to 800C (1472F). When using an ethanol blend fuel with high ethanol content in high-performance applications, a colder heat range may be necessary. Indexing is done by placing (usually copper) washers of varying thickness on the spark plug shoulder, so that when the spark plug is tightened, the plug will rotate a certain amount, and gap will point in the desired direction. #6.

Relative position of the insulator tip to the end of the shell (projection), Continuous low-speed driving and/or short trips, Reduced compression and oil usage due to worn piston rings/cylinder walls, Insufficient tightening torque and/or no gasket, Fuel octane rating too low (knock is present), Continuous driving under excessively heavy load, Insufficient engine cooling or lubrication. Outlets and voltage differ internationally and this product may require an adapter or converter for use in your destination. varies according to manufacturer. ($). Just by looking at the plug won't do anything because the color can mean many things like ignition timing and much more, here's how ur properly read a plug. Product Details. Some basic structural factors affecting the heat range of a spark plug are: The major structural difference affecting the heat rating is the length of the insulator nose. Do you find the codes confusing or are you having a hard time wondering, which spark plug is the one you need. Pre-ignition will dramatically raise the cylinder temperature and pressure, which can melt and hole pistons, burn valves, etc. Carbon fouling occurs when the spark plug firing end does not reach the self-cleaning temperature of approximately 450C (842F).
