We were wondering why my '94 has so many plug wires.
As for why, more complete combustion. There's lots of theories out there on what is going on but it's simpler than most imagine... It's simply just to get spark on both sides of the piston, the coils fire at the same time not offset and they're even waste spark so they fire on the exhaust stroke (at least until there is a cam sensor in the system) since it only knows when cylinders 1 & 4 and 2 & 3 are at TDC basically not which cylinder is at compression... You can mix and match plug wires for those two pairs as well if it helps the wire routing...
