Discharge Boxes

[Zable49]

Hello again everyone,

Got another question for anyone/everyone. I am looking at discharge boxes for the future and I was wondering if there is trully a difference between:

Summit Racing Street & Strip® Multi-Spark Digital Capacitive Discharge Ignitions SUM-850610

And

MSD Ignition 6425 - MSD Digital 6AL Ignition Controllers (or anything along those lines)

Dont get me wrong, I see the numbers are different but do those really cause that much of a difference on the street? Its not like Im going to be racing at the track with my 3/4 ton.
