Spark plug wires

Spark plug wires (also called high tension leads) are electrical cables used by older internal combustion engines to transmit high-voltage electricity from the distributor to the spark plugs . Tension in this instance is a synonym for voltage. High tension may also be referred to as HT.^[1]

Many modern engines use coil-on-plug ignition, a design that does not use spark plug wires.
