    Me and a buddy were talking. Is it worth it to run one heat range cooler plugs in an N/A 3800?

    No boost

    No need for colder plugs.

    i run colder but i have done lots of tuning to mine and always run near the KR limit on the car. if it is stock run stock heat. if you scan and see you have kr and cant tune. higher octane and colder plugs could help.
