Well, I am running 55s, but will probably go to 6s next set, as I am running lots of auto-x and open track.

That makes no sense...

A colder plug resists detonation better because it retains less heat.

For choosing a plug's heat range you want to run as cold a plug as possible without causing it to foul out because it's not hot enough to self clean.

A plug's heat range is basically it's ability to transfer heat to the cylinder head and it's water jackets. Therefore a colder plug transfers more heat and as a result has lower cylinder & plug temps. (I.E. ideal for high CR or Forced Induction)




Hotter plugs burn out faster, right? If it burns out it cannot melt a piston... After a few beers this evening, I am in no shape to fully explain, but there is some basis for my statement. It is beer not crack!

1. Not exactly. Yes it will wear faster dependant on it's heat range.

2. They have nothing to do with each other.

If a plug fails the cylinder gets saturated with un-burned fuel. That's not good for many components!

Also a hotter plug is much more susceptible to detonation! That's what burns pistons, cracks rings, etc.

A colder plug is less susceptible to detonation but is more susceptible to fouling out (see details in my last post!)

Anyone want to help me out here? I'm curious as to how to find out what gap size to run.

I mean how do you determine what gap size... Like if you have a car with certain compression or combustion chamber size or displacement?
