I am certified mechanic with 18 years experience. My personal truck is where i tried this kit out, and so far they are working great. I've been using the truck daily and the coils seem to be perfect. the plugs being OEM well they are working fine. knowing the price of an individual coil from motorcraft or the auto parts store aftermarket, i was skeptical of these being that this kit for the plugs and coils is cheaper then the list price for 1 motorcraft coil. but they are working fine. i had 2 coils that were miss firing and the truck now runs like new. who knows how long they'll last but im happy with them!

Had this package installed in my Ford F150 4.6 litre pickup. So far, so good. I thought when I made this purchase that the coils were also Motorcraft, they are not. Time will tell if they are of good quality. Package did not indicate origin of manufacture but suspect they were made in China. Do not like chinese knockoff products. BUY U.S. MADE!

The Motor Craft Plugs are designed for specific Ford engines to provide maximum performance. A shop previously installed Auto Light Platinum and they run 3,000 miles and started misfiring. Happy Camper!

I put these on my 2005 mercury grand marquis and it shifts better, takes off better, etc. Didn't realize that just changing these would make such a difference.

I bought 8 COP and 8 plugs as a package deal. Installed the parts and fixed my misfire issue. Parts are good quality and so far so good. I would recommend buying where you can replace all your coils and plugs for the price of 1 coil at your mainstream auto parts store.

I highly recommend this product. It fixed my problem when my mustang was missing nd made it run like a brand new one for only a fraction of the cost.

These coil packs perform properly. If you are looking for a shorter term solution to firing issues these may do the trick. I do not know how long they hole up. I have had them installed several months and am just beginning to have firing issues again. Do not know if it is the plugs or coil paks I would recommend buying again..

I have sets of these ignition coils in two 2000 F250's that I drive. Have yet to have one fail. I have used many other brands (Accel, Granatelli, etc.) over the last 13 years and these AC Delco have proven to be the best value and most reliable. As an added bonus, they also come with the Motorcraft spark plugs. Both my trucks have the Triton 5.4. I ordered the sets of 10 to have 2 extras on hand for each truck in case of failure......which has yet to happen. Take my word for it. These coil packs work excellent. One of my F250's has 411,000 miles on it so I have had some experience with coil packs.

I have been running these for a week now. The quality seemed good and the fit was good. My truck is running great again, only time will tell how well these hold up.
