Alternate Products Available. The two most common causes of spark plug problems are carbon fouling (< 450C) and overheating (> 800C). In identical spark plug types, the difference from one full heat range to the next is the ability to remove 70C to 100C from the combustion chamber. This may account for the plugs not having the exact same heat ranges. However, if the gap is too large, and the ignition system cant provide the voltage needed to spark across the gap, or turbulence in the combustion chamber blows out the spark, misfires will occur. The durable plug design also ensures that you're able to get maximum performance from your engine. Also, if too many washers are added, the firing end of the plug will not be as far into the combustion chamber and performance can decrease. Awesome video .
