They were not Herco brand but I did have a failure of an aftermarket D580 coil.  I replaced them with AC Delco D585s after that.

Hi Guys

An ebay store in the States is selling D580 coil packs under the Herko brand for $15USD each.
I currently have Renesis coils and was planning to change to D580 fired by my EC2. Has anyone had failures of D580 coil packs and are there D580's and D580's.
Is anyone aware of cheep copies that may not be up to full spec?

Thanks
