I'm not sure i would venture away from stock when it come to the electronics. When DaveR and I changed my head last year my plugs were so far gapped that my feeler gauge didn't go that high. We had a disscussion about how the truck was running like that and there was no ill side effects. If the stock coils, working properly, could create a spark to jump the distance there is no reason to go aftermarket. When the time comes and my stockers fail, I'll be looking for OEM unless cost makes it silly to stay with them.
