Ignition leads or wires as they are called in the US.
They perform a very stringent and tough job carrying high voltage or HT from you coil or distributor.
Now here is the rub they may look OK but,they will fail gradually so simply replace them after say 15 000 miles.
One nice neat test for failing leads is to wait until it goes dark lift the bonnet start the engine and let your eyes adapt.Any leaking HT will stand out like a sore thumb,these leaks will show upon an oscilloscope but it is a free method of checking.Any signs of arcing then replace all of them.
