Stock LS1 coils =
MSD Blaster coils =
Truck LS2 coils =
Truck coils are the same on my Hyundai
Truck LS2 > MSD > LS1
Embarrassing that the Hyundai 4cyl has better spark then a V8
They all lick
But... if you wanna replace em. and money is an issue, Truck LS2 coils win hands down
Truck LS2 = 2x LS1 (power wise)
MSD is just plain wierd - dual spark is fine, but not at reduced secondary current draw. But they do idle nice
