To keep ignition noise down, most modern cars use resistor-type spark plug
wires.  Alternatively, resistor plugs can be used.  Without one or the other,
ignition noise will be heard.  You should check out the spark plug type you
used top have, as well as the new plugs, to see if they were/are resistor
plugs.  If the old ones were but the new ones aren't, that probably implies
that the wires aren't resistor wires (I assume the wires weren't changed?),
and that you now have to change either wires or plugs to resistor type.
The usual approach is to have resistor wires, not plugs.
