is if custom dwell timing is necessary. Some say without tuning the dwell time they won't function to full capacity and aren't much of an upgrade. I'm not looking for an upgrade but more of cheaper/more robust replacement. I think I'm dealing with some weak coils but not certain yet. Would be nice to eliminate the ptu also.
From what I've read the ls coils that are square, not round, are the ones you want. I believe this is the part number: 12558693. Is that what you have found aswell?
