Ignition Lead - Bosch Australia

A4A4 | Ignition Lead OverviewIgnition Lead OverviewReliable ignition is absolutely imperative if today’selectronically controlled spark ignition engines are tooperate efficiently and without trouble. Ignitionmalfunction leads to misfiring and therefore not only toloss of power and increased fuel consumption, but alsoto a worsening of the exhaust-emission figures. In themost unfavourable cases, the catalytic converter can alsobe destroyed.Reliable connections between the high-voltage ignitioncoil and the spark plug are critical if the ignition energy isto be transferred reliably. Bosch ignition leads aremanufactured to Original Equipment specifications todeliver the following requirements: Contact stability High-voltage strength Resistance to chemical attack Immunity to electromagnetic interferenceBosch ignition leads provide outstanding contactstability. Even though the spark plug terminal studs arestandardised according to ISO, the push-on and pull-offforces are specifically matched to each vehicle model toensure that each lead is easy to install withoutcompromising performance. By using appropriate design,selecting only the best possible materials and applyingcontrolled processes during manufacture, Bosch ignitionleads avoid the issue of arcing at the plug-in interfaces.With an extensive range of vehicle applications andmarket leading performance, Bosch ignition leads are thefirst choice for engine management specialists.When removing ignition leads, we recommend thatthe lead is always gripped by the boot, not the cable.The ignition should always be off and the engineshould be cold.Bosch Automotive Aftermarket 2009 | 2010
