Wear on ignition cables

Based on their installation position, ignition cables are subject to high levels of stress, which leads to wear on ignition cables.

Due to their installation location, ignition cables are subjected to high stress. As they advance in age, the brass and stainless steel contacts oxidise. The electrical resistance of the cable increases - and with it the risk of failure of the ignition coil.

Ageing process of the casing

The casing also ages. Because plasticisers escape from the plastics, they become brittle over time. High temperatures and contact with oil or fuel vapours can accelerate this process or even cause the plastics to dissolve.

Damaged insulation causes the ignition voltage to flow to ground. This would result in misfiring, rough engine running and unburned fuel in the catalytic converter, which would then be damaged during post-combustion.
