The 2004 to 2008 Ford F150 Triton V-8s have an issue with removing the spark plugs. They get carboned up and are a two piece design. I want to use Berryman Chemtool to penetrate into the spark plug threads to help disolve the carbon as well as free up any corrosion on the spark plugs threads. Do you think the B12 Chemtool will help in this area? I have used Berryman for many years. Thank You
You can certainly try soaking the threads in Berryman B-12 Chemtool Fuel System Cleaner (part #0116) to dissolve the carbon. However, if that doesn’t work, you might have more success with a proper penetrant like Berryman Professional EZ Doz-It (part # 1612), which has an optimized blend of solvents, penetrants, and lubricants.
