Trying to find a hotter plug for a banshee. I can find the plugs but their are no cross reference #. Anybody know the # for a hotter ngk plug. The stock one is BR8ES, so whats the hotter plug #? thanks

 

NGK's site Click there and look on the bottom left it says ngk numbering system that will open a window and explain it.

 

BR7ES is what you are looking for, the lower the center number the hotter the plug, and the higher the number the colder the plug

 

What are the benefits of using a hotter or colder spark plug?

 

A hotter plug will give you better low end power and will melt you pistons on top end.

 

well.....not quite.
Spark plugs dont generate heat, they just remove heat. A hotter plug retains more heat than a colder plug, which if you have problems with deposits on the plug, will help to burn them off. If you have an older tired motor, and oil is geting by the rings, a hotter plug will help buy time til you rebuild the motor.

 

I was talking about my banshee when i put in hotter plugs and burned a hole in my pistons [img]i/expressions/face-icon-small-sad.gif[/img]. But they were splitfire plugs.
I will never use splitfire plugs in anything again![img]i/expressions/face-icon-small-mad.gif[/img].
