NGK Spark Plugs (USA) was established in 1966 as a subsidiary of NGK Spark Plug Co., Ltd. of Japan. Its corporate headquarters was first located in California and then moved to its current location in Wixom, Michigan. The company's name was changed to Niterra North America in 2023. Niterra produces both spark plugs and oxygen sensors in Sissonville, West Virginia.

Niterra established its first European subsidiary, NGK SPARK PLUG (U.K.) Ltd. in 1975. In 1979, its second European subsidiary, NGK SPARK PLUG DEUTSCHLAND GmbH, was founded in Germany. Ten years later, it was renamed NGK SPARK PLUG EUROPE GmbH when it took charge of operations in Europe. In 2017, its remit further expanded across the EMEA region. In April 2023, the English-language name of the company was renamed Niterra.

The European division has been operating a dedicated R&D unit since 1990. As well as designing and testing new prototype automotive products, the unit develops technologies to combat issues such as vehicle exhaust emissions. It also provides technical support to car manufacturers in the EMEA region.
In 2017, the company opened a new European Regional Distribution Centre in Duisburg, Germany. It covers 21,000 m² of shelf space, has a team of around 100 employees and supplies customers in 44 European countries.
In 2018, the company became a shareholder of the automotive Aftermarket data firm TecAlliance.
In May 2024, Niterra moved its EMEA Regional Headquarters (RHQ) within the city of Ratingen to Balcke-Dürr-Allee 6, which is situated in the newly redeveloped Schwarzbach Quarter. The move is in response to the company’s sustainability goals and a decision to offer hybrid working patterns to its employees.
