Can't prove that by me. Had an MSD box on the 64 Barracuda and started having problems, so I put the old Chrome box back on it, and it was a whole new car. Trashed the MSD box and never looked back. And that was in the 80's or 90's.
I have been lucky in regards to most MSD products. I only recall one components failing out of probably 50 or more I have owned and installed. But I have ready horror stories about problems with them. And if the OEM works for you stick with it.....
