Copper plugs conduct better than platinum. Platinum's
only advantage is durability. Copper plugs have the
added advantage of being very cheap. Multi element
plugs don't do much either, since the spark doesn't
actually divide (like in the Splitfire commercials) it
just jumps to one half of the electrode.
Wires won't add any power but can keep you from losing
power. Magnecor doesn't claim to make power--they
claim that their wires will absolutely not interfere
with your electronics. This could explain why the
Alfa from a previous post ran smoother.
