$210 per coil? that's the highest I've seen anybody claim. At the Ford dealer they're $98 per coil for oem motorcraft. You got shafted on that one. If you watch Ebay quite often there will be someone selling a lot of 8 OEM Motorcraft coils for reasonably cheap, even cheaper than the auto part store brands! I found all 8 several months ago for $175 and replaced them all in about 2 hours. Once your coils start going bad, they seem to drop off like flies.
