Best price around for stock replacement, but be prepared to spend some time!

American Muscle by far had the best price and fast, free shipping for these plugs. That being said, I've been a mechanic for over 20 years and this spark plug change was the most difficult ever! Be sure ...

how do you tell if your mustang 2008 has the brown or black coil boots?

al66 Year: 2008 Model: GT

  • If your Mustang was built after November 30, 2007 Ford changed designs of the spark plug. They are a completely different thread than used from 2005 until the transition sometime in 2008. If your 2008 Mustang was built in 2008 you can identify which plugs you have by looking at the boot color of the coil pack. Black boots are used in 2005 to mid 2008. Brown boots are mid 2008 and newer. You need to remove one individual coil pack located along the intake manifold an head. There should be an electrical connection to pop off and one single 8 mm screw holding it in place. Be sure to blow and dirt off the area before removal.

What size socket do I need for Ford Motorcraft OEM Spark Plugs (05-08 GT)?

mustangt08 Year: 2008 Model: GT

  • 9/16 deep well socket plug or regular deep well, but you will need a pair of long needle nose pliers to pull the plug out.

I have a couple questions regarding these plugs 1) Are these 1 piece? I don't want to put the 2 piece back in and run the risk of have the carbon snap off issue. 2) Do you really need a special 9/16 plug socket or will a regular deep socket work? Thanks in advance.

    American Muscle's GREAT customer service comes through again!

    I drive an 06 GT as an every day driver, and it recently hit 70k miles. When I was on the highway for a road trip, I got a misfire code so I figured it was time for a tune up. I researched what everyone said about the OEM plugs breaking off and needless to say, after a 2 hour soak of PB Blaster I still only got 4 out of the 8 out cleanly. I ordered the removal tool online and it worked like a charm... But that's all besides the point! lol So I ordered these because of the amazing reviews and the price! WELL... we installed them, went to fire it up, and it ran horrible! At idle it sounded like I had a performance cam installed... I was getting misfire codes on 4 cylinders. I could not figure out the problem... Finally, after some guess and check, and putting the old plugs back in where there were misfires, it ran normal again. So I immediately called AM to see what they could do to help. They sent out a whole new set of 8 that same instant and they made it out to me in a day and a half! I sent back the old ones with no cost to me! So fingers crossed, we installed the new set of 8 and... WOW! She was purring like a kitten... The power I gained back just from the plugs is amazing. Had I known that's where a lot of my power drain had been, I would've done this 20k miles ago! Don't wait till the 100k miles like the manual suggests. You'll be in a world of carbon deposit hurt! Have to thank the staff again at AM... Hands down the best customer service I've EVER experienced!

    American Muscle by far had the best price and fast, free shipping for these plugs. That being said, I've been a mechanic for over 20 years and this spark plug change was the most difficult ever! Be sure to get a copy of Ford TSB 08-1-9 and purchase Lisle tool 65600 before you start. My 2007 Mustang GT had 110,000 miles and gas mileage hadn't been great lately. I removed the coils from the driver / passenger banks of the motor and blew out all debris with compressed air, then tried to remove the first plug, but it wouldn't move. I sprayed WD40 and managed to remove the hex and threaded portion of the spark plug. The remainder of the plug (ceramic portion) did not come out. What happens over time is the carbon between the cylinder and plug seize it in place, due to such a close fit on the 3V heads. The plug ends up breaking and you need the Lisle tool to get it out. The tool gets the broken plug out in about 5-10 minutes. The TSB recommends backing the spark plug out 1/4 turn then spraying carburator cleaner into the spark plug access hole, until it covers the hex and allow to sit for 20 minutes. The cleaner breaks down the carbon and allows removal of the plugs without them breaking in the head. The Lisle tool was abou $60, but I didn't have to remove the head. Plan on about 3 of the 8 plugs breaking in the head. Have fun!

    Removed/Installed with no issues

    After learning that the local dealership wanted $650.00 to replace the plugs in my 'Stang, I decided to do the job myself and replaced mine at a little over 75k miles. On the advice of a Ford mechanic I ran 3 tanks of gas treated with Lucas gas treatment through the engine prior to removal. There were deposits on the metal shroud(the part prone to break), but the Lucas treatment did an excellent job and reduced the deposits to a powder soft coating that allowed the plugs to come out without issue. At 75k miles, I noticed the electrodes had worn down considerably, and I also installed the Accel coils during reinstallation. With the combined effect of the fresh gaps of the new plugs, and the addition of the Accel coils, I noticed a considerable power gain after the initial test drive with no error codes whatsoever. Between the great price of these plugs from AM, the Lucas gas treatment, a tube of anti-seize and dielectric grease for the new coil boots, my plug replacement cost me a grand total of a little over $100.00, a far cry from what the dealer wanted.

    Got my spark plugs installed by Ford Dealership. Ford was going to charge me $200.00 for the spark plugs I got them here for $69.99. I plan to come back here for all my parts. American Muscle...you are the best!

    OEM or Bust

    I purchased these plugs along with a fuel filter to tune up my GT. After reading a ton of forum posts on how difficult it was to remove the original plugs, I'm glad I let my dealer do the job right! After getting her back today, I can honestly say it was money well spent. $69/set on AM versus $25/plug @ the dealership! No brainer! If you are on the fence about aftermarket plugs vs. OEM, Go OEM. These are THE only choice when it comes to spark plugs. This is what the doctor ordered!

    oem quality

    I bought these to replace my original oem plugs at 45000 miles. The old plugs looked great when i removed them, showing that the oem quality is great. Also, I did not have any issues removing the old plugs. One of the few times when I'd say oem is better than aftermarket.
