I have tried to do some research, but haven't had much luck. I am curious to know if anyone has or is running copper spark plugs on a NA setup? I have read that they don't last as long, but still not sure how long they should last and how often they should be changed? 15,000? 30,000? They are better for conducting electricity so i was thinking of giving them a shot and changing them every 30,000 miles. Can anyone provide any input on their experience with copper plugs?

I am not looking for a debate on why i should use one over the other, just looking for an answer on copper plugs.

 

Bump!

 

Running copper ngk plugs...no issues here, would think the change interval is anywhere between 35-50k whereas platinum would be double that

 

Did you notice any benefits? Did you go +1 colder...?
