Does anyone run copper spark plugs in there 6.1 . I used search feature but didn't find a lot of specific info on it... If anyone does do you have a part number I could get...doing tune up thus weekend and always preferred copper plugs to the lazy long lasting platinum plugs...

So has anyone here using copper cheapie plugs 1 step colder that
runs 10's or faster? I replace my plugs monthly just because and
I think the plat's are waste of money and tough to get in a pinch.
So which ones are you running these days Winkster?

I don't think you can get 1 step colder in copper. I have a set but since I re gapped my iridiums I've had no issues
