NGK Spark Plug Co., Ltd., founded in 1936 in Nagoya, Japan, has been a global leader for nearly a century in ignition technology and sensors for the automotive industry. Since 2023, the company operates under the name Niterra Co., Ltd., but the NGK brand remains the commercial name for high-quality automotive parts such as spark plugs, glow plugs, lambda sensors, and NOx sensors. These components are essential for optimal engine performance, efficient combustion, reduced pollutant emissions, and extended engine life.

Starting in 1958, NGK began exporting to Europe, playing an important role in the global automotive aftermarket. NGK’s extensive product portfolio includes spark plugs for gasoline engines, glow plugs for diesel engines, various sensors such as lambda and temperature sensors, as well as technical ceramics also used in industrial applications.

With the rapid developments in automotive technology, such as the rise of electric vehicles and stricter environmental regulations, Niterra has adapted its strategy by placing strong emphasis on sustainability. The company aims to achieve full carbon neutrality in its production and operations by 2050. In this way, NGK/Niterra intends to maintain its leadership position in the sector and contribute to a more environmentally friendly future.
