I have a 2008 GT with 18K, took delivery on 8/30/07 so most likely I have the bad plugs and would like to get them out now.

Going with Brisk, but what heat range should I choose?

Not many Mods:
JLT CIA
93 Bama Race Tune
SLP Loudmouths

Thanks

You should absolutely positively stay away from the brisk plugs and just use the autolite...

For your mods, you don't need the HT0's - the HT1's will be fine.

Before you ask, the answer is...

because they burn and foul too easily and they are also prone to break at the tip easier.
