Jacob’s ignition testing. Thanks to Newbomb Turk….

It’s also hard to find an area or condition where there isn’t a Benefit to having a hotter spark but it becomes a issue is it really needed and how much does it improve the combustion.

A combination of hotter, longer, larger and multiple strikes is the winner and nearly always improves mileage, power and lower emissions.

It’s super hard to improve on today’s ignitions.

So… when is your t to hot? Good question! I guess if your burning out parts before there normal life span would be a good indicator. At least for most applications. All out racing can use its advantage while not caring if there going through a distributor cap a year. The typical guy on the road may consider that way to much.

Your call.
