There are a crapload of questionable D585 knock offs out there. Real GM oem coils are REALLY expensive.
My personal second hand experience of failures , two sets-part of torquehead kits, one set bought from an online vendor.
Some DOA , some died in short order.
Those cars the quick fix were sets of Junk Yard coils.
The one car i did with D585s we used over the counter coils from a reputable local GM dealer and no issues.
My point to this ???
If you start chasing running and misfire issues on your new coil near plug conversion , dont ASSume it couldn't be your brand new coils.
