BPR5ES Vs BPR6ES Difference Between BPR5ES & BPR6ES SparkPlug

What is the difference between a BPR5ES and a BPR6ES spark plug?

Although almost all the features and functions of the BPR5ES and 6es are pretty similar, there is still a slight, negligible difference. The BPR5ES runs much hotter than the BPR6ES because the 6es have an additional stage in their heat range.

The BPR5ES have 5 stages in their heat range where the lower number in the range determines a hotter plug and the higher number in the range indicates cooler spark plugs. And the BPR6ES has six thermal ranges where the 6th number in the range is the coolest.
