Well, I'll have to admit it, MSD Coils just might be junk. Got mine in december of last year, installed them end of Jan/start of Feb and I just burnt one out. It lasted about 23k miles. MSD will not honor its warranty through Amazon or "other 3rd part vendors" because there are "too many to keep track of". It is certainly possible that I got one from a bad batch as that does happen on occasion. The good thing is amazon will be refunding me the cost and refunding my cost for installation so that was nice, but I will be going back to oem when my set comes in next week.
