            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.

            They sent all 8 but unfortunately American muscle did not clear all of their inventory out of the recalled motorcraft plugs...Luckily just 2 broke and I was able to replace them...thanks to autozone.

            Spark plugs

            These spark plugs was just what I needed. My 06 GT is running stronger and smoother. I didn't have any problems getting the old plugs out. I did pre-soak each plug with penetrating fluid for awhile before trying to remove them. Make sure you put some anti-seize on every plug before reinstall.

            Great price

            Do not attempt to install these yourself on an '05 or '06 GT unless you have an extractor tool. 2 of the old plugs broke off at the electrode, requiring the extractor tool to remove. I used sea foam to loosen the carbon buildup around the electrode, but still broke 2 plugs. The new plugs are a great price from AM, much cheaper than the dealer price. I've been told that the problem has been corrected on ,07 and later GT's.
