They should work fine. I just felt that
for a system set up for maximum spark power, I didn't want to have a big
resistance in the plug. I have no idea whether you would ever
notice the difference. I expect Paul Yaw
would.
The
resistor is there as a "ballast" to limit the peak current. You
need high voltage to strike the arc, but once the arc has formed, the
resistance across it is low and it takes very little voltage to sustain
it. Without the resistor in the plug, very high current flows, eroding
the electrode and shortening the life of the plug. Also, the high current
produces a high magnetic field, causing radio interference.
The
resistor also helps to increase the duration of the spark. There is a
fixed amount of energy stored in the coil for each spark. Without the
resistor, a high current flows. The energy is then quickly spent,
resulting in a shorter spark duration.
Additionally,
you can "burn out" some types of spark plug wires by using
non-resistor spark plugs. The wire can't handle the extra current and
goes open-circuit.
Most cars
have "magnetic suppression" type spark plug wire these days. It
is a long coil of thin wire wrapped around insulating fibers. It acts as
an inductor in the circuit. This tends to make the current much more
constant during each spark.
With
electronic ignition, it is not uncommon to have both magnetic suppression
wire AND resistor plugs. They act in concert to limit peak current, to
smooth out the average current, and to reduce radio (and computer)
interference.
If the
coils and ignition control module you have selected were designed to use
magnetic suppression wires and resistor plugs, you would probably be
smart in continuing to use these type plugs and wires. The higher peak
current from non-resistor plugs can also damage the coil or ICM if they
are not designed for that use.
Just my
eight cents. :^)
