ok, so gap the plugs to .044".

wires are probably the spiral wound type, which have a relatively small DC
resistance but a greater impedence at high frequencies. the result is a
higher spark current while still filtering out the high frequency
components, which would interfere with AM reception, possibly the ecu, and
generally annoy and attract the coppers.
