The value of the leads is normally marked somewhere on the lead, usually in the format 15k/m. This would mean 15 kilo ohm per metre, so you would measure the lead and pro-rata the reading - for example if your lead is 500mm long then you would expect 7.5k ohm +/- 10%.
Remember also resistor leads and plugs are an essential (and required by legislation) means of suppressing RFI by reducing the 'ringing' of the L/C circuit that is the ignition coil - for those who are saying WTF? the equipment that Marconi used to first transmit across the big pond was just like our ignition system and our interference was his signal.
