Yes. Generally called spark plug wires in this country. They may be a

It will, but they're concealed in one tube.

No concealment on the Toyota. It has Coil-on-Plug ignition.

Why do they tend to put the coils on the plugs now instead of having one
big coil?

The last car I inspected may have had that, I'm not sure, all I know is
there was a bar that clipped over all the plugs, with one thick wire
leading to it.

It eliminates the moving parts of the distributor and the high tension
wires. Even without the old mechanical points, that is still a couple of
areas of potential failure. The ECU is capable of delivering a timed pulse.
