I caught a "Shade Tree" mechanic show on TNN yesterday... Cool show IMHO.
Anyway, they were building a HiPo engine and they used colder plugs due to the
high compression of the engine... They said the worst thing that would happen
if they were too cold is an increase in carbon fouling on the plug...
A wicked cool part on one of their shows was how they cleaned out the fuel
injectors and TB on an 4duh P/U. They used a "system" by 3M that looked
incredible! They didn't mention how much it cost (and you know what that
means!) but it was really trick and didn't involve removing anything but the air
hat, some vacuum tubes and disabling the fuel pump... I think I even wrote the
number down for info. if you want it.

After installing the MP perf. comp on my '95, it was
pinging on WOT burning ~100 octane.(3/4 tank with 104+
booster) so I decided to put in colder plugs.. she'll
still knock a little bit at WOT (limited mostly to
going up hills). I'm thinking the pinging is due more
to carbon buildup than anything else..
should I take out the colder plugs if I don't need them
after decarbonization? Are there any ill effects of
running a plug that is too cold?
