    The best most efficient plug will be able sustain the spark at the largest gap- giving more reliable fuel ignition! Bosh platinum make a good plug but I doubt it will make much difference unless you have a real high performance engine

    With all cable its the same- the lower the resistance(ohms) the better the electricity will flow! what governs resistance is size of cable, amount of strands and materials used( its atomic number will tell you how many free electrons it has to conduct electricity- in relation to the bands on the atomic scale)! but most good quality cable are = and totally ok for the large amount of volts -will not change your engines performance

    Bosch platinums or Nipondenso Platinums work well for people with a budget. As for wires, the thicker the insulation the better they will perform. Standard wires are like 8mm. If you want something a little better try 8.5mm or even 9mm but the thicker you go the more expensive they are. As for the coil, I would not replace it. Coils either work or they don't work, they will not "start" to go out.
