The company was established in Japan in 1936. Nowadays, NGK spark plugs and other components produced by the manufacturer, are well-known around the world. The parts belong to the premium pricing segment and are manufactured in Japan, the USA, France, Malaysia, Thailand, Indonesia, China, India, South Africa, Germany. Thanks to fruitful collaboration with various car manufacturers the company received numerous awards,  including “For outstanding quality” from Audi and “Supplier of the Year” from General Motors.


The manufacturer produces the spark plugs for the engines operating on gasoline and natural gas. Such products are presented in the assortment:

  • With one side electrode and V-shaped groove in the centre electrode. Such plugs construction promotes stable ignition of the mixture even in complicated operational conditions.
  • Multipolar. Presence of a few ground electrodes (from two to four) promotes excellent ignitability and extending  part’s working lifetime.
  • With an auxiliary spark gap. Thanks to the special construction of the spark plug body, ignitability is provided even at presence of carbon fouling on the isolator. And self-cleaning of the plug occurs at reaching 450 °C temperature.
  • Semi-surface ignition type spark plugs. The construction comprises at least two earth electrodes with tapered point. These parts remain effective even when there is carbon fouling and are self-cleaned at every spark.
  • With electrodes made of precious metals. This category includes the parts with the very thin (0.6 mm) middle (centre) electrode with the iridium-alloy tip. They are characterized by low ignitionvoltage, resistance to spark erosion and have the very continuous operation lifespan. Also you can buy NGK spark plugs with the electrode, in which the platinum plate is welded. Use of this material provides constant output of the components during the entire service life, even under difficult conditions.
  • Hybrid. They combine characteristics of the platinum parts and semi-surface type spark plugs.
  • Racing. These are components with the ring-shaped earth electrode. They are resistant to high levels of pressure, vibration and temperature.
