Re: Champion 3X Spark Plug
As far as using 3X plugs for a driver - I took mine apart, cleaned them in carb cleaner, wire wheeled them then sprayed them again with carb cleaner (the factory bluing was pretty far gone, so didn't harm any nice plugs doing this). After they were clean and dry I sprayed them with high temp barbecue black paint. They looked like new plugs when I was done.
