The best bet would be changing the cables with brand new one's instead of used or kabli one's. Mostly used or kabli parts have completed their life like these.
Check for the resistances of the plug wires and if the values exceed the required values given in manual of the car then they definitely need replacement.
The aftermarket wires may cost you around 600-1200-/RS for a normal new set. They also work good.
I am using the ultima plug wires in my car from 3 year's till now they are going good no arcing or loosing of cable's from distributor end/ignition coil/spark plugs.
The OEM wires must be really expensive.
@margallar has faced the issue of arcing on ignition coil he would guide you better about that.
