Chip, I have 3 MSD boxes in 3 of my cars inc the Charger. All of them were made in the USA - zero issues.

I believe they have been made in China for some time now and I'm seeing and hearing the failures have been mounting and becoming more and more common.

I hear Daytona Sensors are super reliable boxes but have'nt used one myself.
