I had earlier postings (last year) concerning the failure rate of the MSD 8224 ignition coils. In the course of a year all three had been replaced, failing one at a time, meaning three returns to Autotronics in ElPaso Tx.
Well the car started running like crap, AGAIN, and guess what a fourth coil gone bad! good thing that I started keeping the OEM coils and a 5.5mm wrench in a box in the trunk.
Finally while talking to the rep at Autotronics, he suggested that there "may have been " a production run problem a while back when Jegs & Summitt and everyone else had these things on B/O! With that said he gave me a RMA number and said to include a short note with that number on it and send all three back and they will replace all three, even though when the coil windings were megged, one one coil proved bad.
Just in case anyone else got any coils out of that run, and is having problems with replacement, ie Jegs told me that I would have to pay for a new coil, time to start dealing with Summitt anyway!

I'd say stick with stockers, or 97+ SC'd ones if you can. They're slightly hotter from reports then the ones your cars came with. Top 3800 race cars have stock coils.

There was a bad run, but that stock should be long used up or returned by now. I had one of three fail. It was replaced at no charge.

MSD coils are slightly cheaper than stock, and are a dependable replacement at this point.

I had an 8224 go bad on me about a month and half ago. I only had the coil on the car for 3 months before it went bad. Last week I had another misfire code and I'm suspecting it may be the beginnings of another bad coil. I know there are flukes and bad production runs, but I might just stick with Delco from now on. If it can be proven that the MSD problems eventually fade away I'll reconsider, but for now I'm a little frustrated. A brand that'* used by some of the world'* biggest racing teams can't be terrible, but I'm not convinced yet. I'm going to try to get a refund for all three coils from Jeg'*; otherwise, I'll see what my options are.
