I got mine from Summit. I changed the plugs at the same time. The car seemed to run a little smoother after, but I'm not sure if it made a big difference. They were listed as stock replacements. The coils are nice quality and packaged nice.
The first set was clearly used...paint worn off around the bolt hole, heat discolored logos, and one was missing a spring which I suspect is why they got sent back.
They initially said they wanted them back and I received the replacements fast after I sent the pics but I've not heard anything since so IDK.
If anyone is already running these/ when some do I would be very interested how they perform to see if it would be worth it to buy them. Also do the stock coil packs “wear out” so to speak as they get older?
Ford coils are a known problem. Very very bad years back better now. But in my eyes I would change them as a tune up part around 80k! Cars don't have plug wires,cap,rotors anymore so $250.00 for 6 new and a touch stronger than stock coils is a win win!! I am in no way expecting to feel anything but not feel a missfire from a bad coil in my near future!!
