Japanese specialist in ignition and sensors

NGK is a Japanese manufacturer with roots going back to the 1930s and has grown into a major supplier of spark plugs to both carmakers and the aftermarket. The brand has extensive experience with ceramics, a central part of any spark plug, and uses that know-how in both plugs and sensors. Under the NTK name, the group also makes oxygen sensors and other sensors that measure combustion and help the engine management keep the mixture right.

NGK’s key products

Spark plugs are the core of the range, from standard copper plugs to long-life iridium and platinum plugs and racing plugs for high-pressure engines. When tuning with a turbo or supercharger, many choose a colder plug that better handles the extra heat. NGK also offers glow plugs for diesel engines, ignition coils and ignition leads, plus oxygen sensors, including wideband sensors used with engine management systems and gauges. See each product for engine fitment.

Frequently asked questions

When should I choose a colder spark plug?

A colder plug transfers heat away faster and is typically used when an engine makes more power, for example with a turbo, supercharger or nitrous. On a stock engine you should generally use the heat range the manufacturer recommends.

How long does an iridium spark plug last?

Iridium plugs generally last longer than standard copper plugs because the electrode wears more slowly. The exact replacement interval depends on the engine and its use, so follow your vehicle’s service schedule or the recommendation for the specific plug.
