Well I say that because a leaky alternator will kill a MSD box that has no capacitor in short order. That tip doesn't get the press it is entitled to, but it's the truth. DC voltage spikes will also contribute to an early demise.

I had an MSD coil die right out of the gate (55 miles) and during the diagnosis process I spoke with Bob at ERA. He indicated he has not seen an MSD box failure that has the properly installed capacitor.

I installed the capacitor when I replaced the coil. Time will tell if it protects the 6AL-2 box.
