Hey guys how are copper plugs in our cars??? I know that they don't last as long... Do they perform better and about how long do they last usually?

Better plug but have to change it much more often.

No more than one year before exchange.

Copper is a better conductor though.
The copper plugs should be changed every 10-15K miles.
I use Motorcraft platinum plugs in my mustang because I
don't have to change them until 60K miles or four years.
You can't go wrong with Motorcraft plugs.

yea thats what i'm trying to deside. Either go with the motorcraft platnums or go with some copper ones. I'm looking for a litte more performance anyway and i'm thinking those cheap copper ones aint that bad.

yes that is a copper plug, and I say I WILL change them every 5k, because I have only put around 1500 miles on my car since I bought it 2 years ago. I will change them so often because I run alot of boost, and they are cheap.
