Plugs on a 2009 GT

[jam116]

Have been reading that some of you have experienced some issues with the plugs
breaking off when you change them?
Is this a problem on the 2009 of has Ford fixed this?
If it is still an issue is there a fix we can do?

Ford changed out the plug and head design during the 2008 model year. The plug is now 1-piece and the problem has been eliminated as far as I've heard.

I was worried about the same thing happening to my 09 bullitt. Everyone has told me that the problem has been solved by the new design as stated above.

Thanks..
That is good news!

Any car made in 08 or newer will have the new head casting with the one piece plug. You can check on your drivers side valve cover there is a code that will either have an AA or AB in it. AA is two piece plug and AB is the newer one piece.

Well c@ap!....
The GT is a 09 but has the code of AA ?

I think the AA vs. AB codes are to differentiate the 08s, since the change was made during that model year. You should be fine with an 09.

Agreed. Any 2009 will have the updated heads. Most 2008s unless built at the beginning will have the updated heads and plugs. I'd like to add that this isn't a huge problem. There are way too many "chicken littles" who scream the sky is falling. Yes, It's a bad design. Yes, it can be a problem. If you follow Ford's TSB than you should no problem removing the old style 3V plug. I've done roughly six sets of 3V plugs with no problems.

an easier and more accurate method is to go by the color of the coil boots. black are the old style, brown are the new style.

What is the difference between the first castings and the new castings? Just how the spark plugs fit?

I have an 08 GT build end of 07 and it has the AA or older style heads.

It's a whole new spark plug design so the heads had to be redesigned to accommodate the change. From what I know, nothing else has been changed.

Ok don't mean to sound stupid but I got to ask..
The part that attached to the plug is black. But I can see a brown colored (plastic looking) part, sleeve right next to the head....
