I am planning my upgrade path for adding ls2 truck coils and I notice that the Delco/Delphi coils are $63/ea minimum whereas I can get a set of 4 of them with bracket on ebay for about $100 if I get Herko brand.

Does anyone know if I can cheap out or it not worth the risk of failed coils in the future. From what I understand, ACDelco coils are made by Delphi, I am wondering if maybe some other brand are factory seconds in appearance?

If I were to try and bargain shop, am I better to use NEW Herkos or USED ACDelco?
