I hate to even ask this because I know the answer but maybe I'm missing something.
In the SE catalog they list plugs for stock configuration and different ones for cam and compression upgrades. I'm assuming the heat range is different. Which is which?
I have upgraded cams, intake and exhaust and am just wondering if a different plug would be better suited than the stock 6R12.

 

`Never heard of such a thing, but it sounds like another spark plug scam to me........

 

I've heard of them don't waste your time. They are worse than the stock plugs.

 

Try a set of V-Rod plugs.

 

What's different about vrod plugs? Hotter or colder?

 

V rod plugs are colder basically better for big cubic inch motors

 

1 step colder than stock big twin plugs.
They helped a little with some detonation I was having with my old hot-rod 95" motor.
