NGK Ignition Leads & Caps Technologies

There are three different types of ignition leads. These types differ based on the materials used for the conductor and the type of resistor required for interference suppression. It is important to choose the correct technology for the specific engine. Only this will lead to good performance of the ignition system. Our part finder helps to find the correct technology. NGK ignition leads' technology 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.
