Motorcraft DG508 Ignition Coil

I have a pretty high degree of confidence that these are the real deal - Ford OEM. However, be careful who you order from. Just because they are listed on Amazon does not mean Amazon has any control on what a seller is actually selling you. I would urge you to either purchase directly from Amazon (Amazon.com listed as seller) or a seller that lists "fulfilled by Amazon". That helps to insure you will get OEM. I went with a "fulfilled by Amazon" seller, Auto Parts Wholesale, to save the sales tax that Amazon has to charge me.I ordered and installed 10 for a 1999 Ford F-250. Each one was individually packaged in an official Ford OEM bag. Each coil had a small amount of dielectric grease already on the tip. Each coil looked OEM with markings. (I did put a small additional amount of dielectric grease on tip.I have had my 1999 20 year old truck for 15 years. I have no idea if the original owner ever changed out coils or not. But, about 10 years ago I had a miss, figured it was a coil, and took it to Ford dealer who diagnosed which coil was bad. I think the coil was close to $75 and labor were $100+. That was 10 years ago before Amazon and others started selling these coils.When my truck recently started having a miss, just occasional but there, sometimes when idiling, sometimes when accelerating, I figured coil again. But, I priced Ford OEM coils all over the place, and Amazon had the best price, even better than the on line retailer with rock in their name. I figured I would go ahead and replace all 10, for just a little more than what Ford dealer would probably now charge me just to replace one bad one.I also replaced spark plugs at same time - auto lite double platinums at good price and rebates from advan auto. My truck is a V-10, and getting to the back plugs and coils is a challenge, especially on the passenger side. But, by removing some parts that were in the way, and using a variety of extensions, I did it without anything going wrong.Suggest you use the magnetic spark plug socket if you are changing plugs - works much better than the rubber one.My truck now runs great - no more missing.

This is a task on an old V10, ended up taking it in, but these worked great. Old engine I'd feeling great. Was worried about knock offs considering the steep discount but these seemed genuine, shop said they were good and they went right into my Excursion no problem. At 80k or more for a new truck, glad to find products that keep the old truck on the road.

Great price, arrived quickly

Quick shipment. As described.

a little waiting on shipping over all good quality

Fixed my problem.

Worked like a charm I my 2008 F150 4.8 liter engine.

I bought 6 of these COPs because I had previously bought 2 from the autoparts store at twice the price. When they arrived, I didn't immediately install them as my 2008 Eddie Bauer 4.6 liter was running OK from replacing the 2 with a misfire. However, I generally like to replace everything at once as to not have old parts and new parts together. I zipped out the old plugs with an impact and went to install the new COPs only to realize they weren't the same. They are genuine motorcraft, but the electronic connection isn't directly across from the mounting bolt, like the originals. It's cantered off to the side and there's no stop on the COP to keep it from twisting in the spark plug well. I thought, meh, I think it will fine. Wrong. EVERY time it rains, I get the dreaded misfire on cylinders 8 and 3 and sometimes 7 from the factory water drainage ports on the hood. I have to remove the COP, blow it out with compressed air and reinstall it. I did not have this issue with the original COPs because they created a tight seal. These do not. I even switched the boots from the old ones to see if that would help, but it didn't. Since the COPs can freely move in the cylinder well with the slightest pressure (even though they are tightened down) it allows the water to seep around the boot. I'm now going to install the old boots back in until I can afford to buy the correct COPs. They should be the DG521 or DG511 depending on the year it was manufactured. DG508s ARE NOT the correct COP for this engine. Amazon should remove this compatibility from its website. I hope this helps someone else from losing money over this misinformation. I should have installed them immediately to make sure they worked, but I didn't and I learned my lesson. 🤦‍♂️
