IGNITION LEADS & CAPS

POWER TRANSFER

SlashesEfficient High Voltage Transfer

Connecting the ignition coil to the spark plug, ignition leads are a key element in the ignition system of many petrol engines. Thanks to NGK SPARK PLUG’s expertise in ignition technology, the company offers ignitions leads and caps that perfectly complement its wide range of spark plugs and ignition coils.

Up to 1,000 ignition leads available

SlashesIgnition Leads & Caps Technologies

There are three different types of ignition leads, which differ based on the materials used for the conductor and the type of resistor required for interference suppression. Only if the correct technology is chosen for the specific engine, which is made sure by our catalogues, good performance of the ignition system is guaranteed. The technology used in NGK ignition leads meets the OE standards of car manufacturers. The NGK SPARK PLUG product range for ignition leads includes:

  • Copper core ignition leads with interference suppression resistor (in the connectors)
  • Carbon resistor ignition leads
  • Ignition leads with inductive resistor

NGK SPARK PLUG caps are equipped with a resistor element made of high-quality ceramic materials. This ensures a constant resistance value with only slight deviation during overload conditions. The casing consists of a robust phenolic resin with extremely good resistance to heat and tensile stress. Special rubber bushings on both ends prevent electrical losses from moisture.

SlashesRequirements on Ignition Leads & Caps

Outstanding insulating characteristics, a high level of heat resistance (up to 200°C) as well as resistance to vibrations and fluctuations in temperature and humidity, are the primary requirements to be fulfilled by top-notch ignition leads. Only if they fully meet these requirements can ignition cables offer permanent reliability under extreme conditions – even over an extended period of time.
