Is there a product that can be used in the combustion chamber that will reduce the amount of carbon build up, and if so will it work on the carbon that is already built up. I have an 06 with 26000 miles on it and am just reading about the problems with the two piece spark plugs and the carbon build up.

For those that have changed out the plugs, what did you reinstall?

I put the Champion one piece plugs in. So far, couldn't be happier. But only a couple hundred miles on them at this point.

Can't answer your question on reducing the carbon build up. I know that taking your car out on the highway for some miles is said to get rid of some of the carbon.

I can't speak for anything to prevent the build up w/o taking the plugs out. However, quite a few people (including me) have taken the plugs out, clean & nickel anti-seized them and then reinstalled the stock plugs. The anti-seize will prevent the build up of carbon and allow you to remove the plugs easily next time.

See this thread (Its when I did it to mine):

Be Careful & Follow the TSB, & Don't use a lot of force to take them out.
