As the main source of power in any petrol engine, a spark plug performs an essential function: It is responsible for igniting the air-fuel mixture in the combustion chamber of petrol engines. This combustion process creates power, which sets the vehicle in motion. To make sure this process runs smoothly, the spark delivered by the spark plug must ignite just before the piston reaches its highest point and the compression is at its greatest.

NGK glow plugs are setting new standards in glow plug technology. Under a certain temperature, the engine will not start without well-performing glow plugs. Therefore, glow plugs are mandatory to ensure a perfect engine start, especially in cold conditions. This is why Niterra is constantly expanding its expertise. There are two glow plug types: metal rod glow plugs and ceramic glow plugs which have special characteristics in regard to thermal behavior.

There are three requirements that top-notch NGK ignition leads need to fulfill: Firstly, outstanding insulating characteristics, secondly a high level of resistance and finally, resistance to vibrations and fluctuations in temperature and humidity. If the ignition leads meet these requirements they can offer permanent reliability under extreme conditions. NGK ignition leads are a key element in the ignition system of many petrol engines.

The ignition coil's design and material must be resistant to heat and moisture in the engine bay and function reliably. Oil and petrol vapours mustn’t be able to harm the housing: This damage to the housing would impair the function. NGK ignition coils use the technology car manufacturers require. The vacuum moulding process ensures a blister-free encapsulation. Each ignition coil is produced in strict compliance with OE specifications.
