It's easier on the ignition to clear a smaller gap, or requires less energy. However you want to say it.

Could ya give me evidence of what "quite a bit of difference" is.

It makes the plug easier to fire. To me if the system is working then run whatever gap ya want.

so if your car is N/A and your running say a, MSD 6AL, gap them at .050 for best results?

N/A 350 LT1 + 6AL + cc305 + AFR heads + NO emmisions; would .045 be a reasonable gap with TR55's then? I've been running Delco plugs for years but now want to try different plugs.

thanks

If you go to the NGK website, they specify 0.044 for all versions of the TR55.

i have acdelco platinums. for some reason ive been gapping them to .045 and throwing em in. is there a benefit to gapping them tighter or will it hurt?

please don't gap platinums, it messes up the tip.
