I was just wondering what you set your spark plug gap too when doing a tune up...  I'm pretty sure the owner manual says the tolerence is from .39-.43...

IF anyone knows, is there going to be a difference if you set your gap to .39 as opposed to .43?  Will the plugs run cooler per say?

Gimme your ideas!

I have platinum spark plugs, magnacor wires and an ignition system. I talked to a bunch of ppl and they told me I could regap them from .4" to .6". This is a big difference. What exactly does it mean? I've been driving on it for about 7 months with no problems and a definate performance increase.
