Alright, I just scored an MSD 6A box for a damn good price... FREE! Now, the 6A doesn't have the limiter on it but that's cool with me for the time being. I was wondering since I have the moroso CAI, Smooth Elbow, Full exhaust and a mild cam along with the MSD OPTI, should I go ahead and wire this bad boy in or would it be more of a waist of my time at the moment? If it makes no since to put it in the 'maro then I'll drop it in the Bronco since it has full forged internals and all the goodies. Cool Beans!

 

I would think that it depends on the cam you have and how reliable/consistent you need your spark to be with your setup. Seeing s you have an MSD opti already and assuming everything else is stock orr relatively mild then you wouldn't necessarily need the 6A. But it wouldn't hurt. It would just add the little bit more stability and control to your ignition system.

 

You can put it in either vehicle, but it won't get you any power

 

I figured as much. What's the deal with them anyways? Needed for higher octain or something?
