        tune up

        Since I bought my GT used, I had no idea if or when the plugs were replaced or turned up, bought the OEM plugs and changed them out as the old did look quite worn and , easy replacement and now she's runs smoother and accelerates much better. It took a couple of hours only because I soaked the old ones for about an hour before pulling them out to ensure they didn't break in two.

        Buy the extraction tool, old plugs will break!

        I followed the removal procedures according to the Ford TSB as well as watching YouTube videos. 2 out of the 8 plugs broke in the cylinder head! Have the extraction tool on hand... it’s worth it even if you don’t break any plugs. New plugs installed with ease! Car started right up. 2006 GT w/ 57,000 miles.
