Spark Plugs for 06 GT

[arcwcb]

Does anybody but Ford make spark plugs for 2006 GTs? I've looked and all I can find are plugs for the V6, and then like 08 and newer or something GT. The only ones for the 06 GT that I've found are the Ford replacement sets and I'd really like to go a heat range colder for the nitrous... Somebody help!

Where have you looked? Aside from online

I use Autolite HT1, and like them so far, HT0 is the colder plug. If this is your first plug change for this car, be careful.

It is, I just rolled over the 40,000 mark. Why do I need to be careful, is something weird about removing them?

 

[ViperNuge]

Do a search dude..............you gotta follow specific procedures to remove them. They are a two piece POS design plug and are prone to breakage. If you break em you then have to order the special tool to remove the stuck part. This is a well known issue and there are stickys on most mustang forums. If there is not one here try s197forum.com

Good luck and take your time...... patrick

Are the autolite HT0 a two piece design too or are the factory ones the only ones that are crappy like that? Is Autolite pretty much the best plug to get for our car?

Plug choices

Both Autolite and Motorcraft are POS 2 piece plugs. Actually, there're the same plug with different lables on them.
Champion #7989 is a 1 piece, double platinum plug that should last a very long time. I have them and I haven't had any problems in over 25K miles.
Brisk makes a 1 piece plug that many like. Be aware though, Brisk plugs are racing plugs with no platinum on the electrodes and by Brisk's own admission, will have a fairly short service life. I think Accel now makes a 1 piece plug but they are stupid expensive, and I don't know if they are platinum or not. Pay your nickel and make your choice.

Any idea where I can pick up a set of the champions?!

 

[GOLDENPONY]

I think I have read Rockauto has them for around $100 a set. I think I got mine from Summit Racing.
Also, the Champions require a different spark plug socket than the Motorcraft plugs that are in there now. I think the Champions take a 9/19" spark plug socket. If you haven't read up on it, do a search on the TSB procedure to remove the old plugs without breaking them. Also, use a thin coat of nickel antiseize on the lower barrel part of the new plug when installing (not the threads). KEEP ANTISEIZE AWAY FROM THE FIRING END OR IT WILL SHORT OUT THE PLUG. Oh, Champions only come in the stock heat range.

I saw a program on tv about the issues with our factory spark plugs and how they are prone to break if your not very careful when removing them, they said to spray a little carb cleaner at the base of the plug let it sit awhile, then crack them loose and spray a little more carb cleaner, let it sit awhile and repeat this process until they come out, personally I think I would use Sea Foam instead, that stuff eats carbon build up like nothing else and the way I would do it would be, to Sea Foam them, crack them loose, spray some more Sea Foam, turn them back in, crack them loose a little more, spray more Sea Foam, turn them back in, crack them loose a little more than the first and second time, spray Sea Foam, turn them back in, and keep working them back and forth, working the Sea Foam down into the threads and beyond.

Best of luck and take your time.

One thing -- You want to loosen the old plug no more than 1/8 turn when you spray the Seafoam stuff in around the base. If you don't slightly lift the plug off it's seat the Seafoam can't get past the seat & wick down to get to the carbon. Good luck Bro! Take your time.

I knew I was forgetting something You are absolutely correct, I specifically remember them saying on that tv show, "loosen no more than an 1/8th of a turn" at a time. I used the word "crack" instead

I'm gunna get the dealer to do em'! The one and only thing I'll get the dealer to do ~ I'm not gunna screw around with this potential nightmare

Be aware, some dealers (like mine) will do it. They told me it would be about $250 for the spark plug change and $50 extra for each plug that breaks.

Sheesh that is sooooooo expensive When I was watching that tv show about this issue and they said our 4.6's with over xxxx miles were the ones most likely have these breakage issues, does anyone know what the miles are? If I remember correctly I think it was something like 40,000 miles and over?

My car has 26,300ish miles and I remember saying to myself when watching that program and they said the miles, I was like "whew" I'm okay for now!!

I will say one thing to the OP: Get a lower heat range plug as you are running NO2! Find the one piece Brisk plugs that have the colder heat range as Champions don't have that.

 

[arcwcb]

Oh I definitely planned on getting a heat range colder, pretty much the N2O is what prompted a quick plug change. This does sound like a nightmare, but I can take my time and slowly work them out. I think I'm going to go with the Autolite HT0s since they can go colder. After i'm done, I'll post on how it went!

I just had my spark plug replace twice with little over 15,000 miles. First time I had dealership install the champion spark plugs. I car brought home that night and had CEL with 4 codes misfire on number 5 and 8.Thought for sure it was going to be a bad COP because it would only hesitate less at low speed.
The next morning I brought the car back to the dealership to have them look at it because just gave them $230.00 to have them replace. They called me back in hour to tell me two of the spark plugs were bad do to the insulator sliding up and down on them causing the miss fires.

So end up replace all the spark plugs again with all new motorcaft ones that cost me another $230.00 plus $160.00 for plugs from dealership.

I ask mechanic how hard it to get out the old plug he said they came out no issues.

So a spark plug change cost a total $731.00 I did send back the champion ones to summit racing so might recoup a $111.00.

 

[arcwcb]

Well, I went with Ford spark plugs, and I've heard that as long as the car has under 50k miles, they come out without too much fight. I do have one more issue though, I've seen a LOT of cars that change the coil packs when they change the plugs, most seem to go to the ACCEL or MSD coils. Is there a reason, like the stock ones suck or break, or is this just a mod for like 5 RWHP that people do?

I just did the first spark plug change out on my 06 GT with 106,000 miles on it. I took a deep breath, cracked them all between 1/8 - 1/4 and used Seafoam to loosen the carbon. They came out with a little squeaking, but all 8 came out fine. The only thing that I did not follow on the TSB was that the car was not completely cold, but had sit in the driveway about 2 hours after my hour drive home from work and engine was warm to touch. I used the champions as the replacements and have had no problem the last 1K miles or so on them.
