Are all LS coils created equal or are some models better than others? I am talking about stock coils. I certainly don't want the expense of replacing MSD coils continually.

I had heard that the truck coils were a little better, but are the wiring plugs the same?

i think they are a little longer, i have truck coils on my car. the wires are about 3 inches longer mabe. they sit up a little higher too, so it might be needed. i think the connectors are the same, i just put msd wires for a 99+ truck on mine

o wait u meant the wiring harness lol, yes, you'll want to get the complete piece off a truck though, the mounting bracket is different, and the wires come out on top instead of the bottom, everything else is identical though.
