At 55,000 it started giving P0300 codes, Multiple Cylinder Misfires.

I don't know if this is a design or manufacturing problem, but please save yourself the frustration I've experienced and don't buy these plugs.
Timeman
In the end, they refused to send me out 3 replacements but said I could simply reorder the plugs.

If you are buying this plug to replace the originals on your Ford/Mercury/Lincoln product, this is one you want. The reason is that the originals are prone to break INSIDE the head. When the original Motorcraft plugs were manufactured, the nut and electrode sheath are machined separately, then pressed together. If you haven't seen them, the electrode sheath on this and the original plug are long. About 3 inches long. As you can see from the photo, the electrode sheath is 2/3 the length of the plug. On top of that, the plugs are recessed into the head to reach the upper cylinder wall. What happens over time is that the sheath rusts to the head and when you attempt to remove the plug, the sheath and nut separate and you have issues.

There is a special tool you can buy or rent to remove the broken off piece but it's a pain because, at least on the back two plugs on each side, you don't have much clearance. Also, if the tool doesn't work, you have to remove the head to take out the broken piece. Not trying to scare you, just informing you. The job is doable and well worth the money you'll save doing it yourself. Ford charges around $300 PER plug, do the math. I did my complete job (coils and plugs) in about 3 1/2 hours. I purposely waited until it was cold outside (40 degrees) to minimize the rust binding factor. I didn't break a plug.

Again, this Champion plug is the one. Make sure you put nickel based anti-seize, (Permatex 77124) available here on Amazon, on the electrode sheath to stop the rust binding when you replace them again in the future. Make sure you have some silicone dielectric available (like Permatex 22058) for the coils. Good Luck!

After paying $300. to get these put in, they only lasted 5000 miles. My truck started running very badly. I bought the tools to do it myself, and found one of these plugs had broken internally and the porcelin had settled down around the electrode so it couldn't fire. I bought the motorcraft SP 507 plugs and put them in.There is a new plug now, the SP 515. Ford Technical Service Bulletin (TSB) 8-7-6 will guide you thru the process. Follow it to the letter and hopefully , you won't have any problems. You should buy the tools listed above, the dielectric grease and nickel anti-seize .Also, I Used PB Blaster to soak the plugs for almost 24 hours before attempting to remove them.This helps to break up the carbon that gets between the plug and the head and cause them to break upon removal. I didn't break one plug getting them out.Good luck. I hope this helps you. I researched and made my plans before starting.

Used these to replace the OEM plugs on 2005 and 2007 Ford F-150's. If you've been paying attention, you know most of them need to be replaced, BEFORE they get too old (IE: "carboned" up). These are a much improved design over the OEM version. Seem to work great, so far, after about a year and 30,000+/- miles. Maybe slightly better gas mileage... A little expensive, but we think it was worth it to eliminate a VERY expensive and difficult future problem of broken off plugs.

I bought these for a 2006 Mustang GT to combat the well know "spark plug breaks off in head" issue. When I tried to remove the factory plugs (about two years ago) I broke several of them and had quite the panic filled day getting them out. I decided to replace them with these when I removed the factory-style plugs recently to reapply anti-seize. My car runs just fine with these and hopefully I won't have to worry about breaking them ever again. I put a bit of anti-seize on for good measure.

As for getting the OEM plugs out, get some Kroil or PB Blaster and add lots of patience and they should come out relatively trouble-free. When I removed the factory-style plugs (which I had put anti-seize on) to put these in, they came out extremely easily with some Kroil.

I bought these to replace the defective 2 piece OEM plugs that break off on my 2005 F150 V8. These are specifically designed to prevent breakage upon removal and can handle a lot of torque because they are a 1 piece design. The dealer wanted to install so called improved Motorcraft plugs and I said no way. Once the old plugs were out and these were in, the engine seemed to run a little better. Buy the way, the longer you wait to change the plugs, the more likely more will break and Ford will make you pay extra for labor to use the extraction tool. At 62k miles, 4 of mine broke.

Ordered eight #7989 plugs for our 2008 F150 3 weeks ago. I sent 6 of them back as the ground straps were badly bent and not lined up with the electrodes. This is a common problem on these 7989 plugs. Replacement 6 arrived and I sent 3 back for same problem to be exchanged. 5 days after sending the 3 plugs back, Amazon emails me to let me know they will not send me any more plugs and simply refunded my money. I phoned Amazon customer service in India and began a hour long phone call about poor customer service. They mentioned that they were concerned about product quality and might take the plugs off their web sight. What a load... they were still for sale on their web sight and had even raised the price. In the end, they refused to send me out 3 replacements but said I could simply reorder the plugs. OK, I'll give. Since my initial order 3 weeks ago, the price had gone up $3.66 each. I asked them to honor my original purchase price when I reorder as my original order had not been fulfilled yet. Customer service agent and his manager both flatly refused. Bottom line, terrible customer service, terrible return policy, and wont even honor the customers original purchase price. Amazon gets a solid "F" on this one.

UPDATE: After 2 months and 1500 miles, one of the Champion 7989 spark plugs failed internally and generated a check engine light with a "cylinder 2 misfire" code. Replaced spark plug and all is well but it doesn't bode well for the reliability of these plugs. I'm a 25 year ASE tech and while Champion's problem solver 1 piece design has addressed Motorcraft's 2 piece plug disaster, it has introduced poor quality control and reliability, something that was never a issue with the Motorcraft plugs. For what its worth...
