Research & Development

With major R&D centres in Japan and the USA, NGKs European research and development work is based at the Technical Centre in Ratingen, Germany. This facility, established in 1990, has continuously expanded to provide technical support to the European automotive manufacturers.

The NGK Technical Centre covers an area of approx. 2,200 square metres and cost approx. 15 million Euros. It has three modern engine test rigs for endurance and application tests, together with cold-climate chambers in which engine and chassis can be cooled down to -30 degrees Celsius for analysing cold-start performance. It also has comprehensive equipment for carrying out full exhaust gas emission tests.

Today, NGK has benefited from this investment in Europe by being the OE supplier of spark plugs and or glow plugs to most vehicle manufacturers in Europe including Audi / Volkswagen, BMW, Mercedes, Jaguar, Fiat, Renault, Peugeot and Vauxhall.

With worldwide legislation demanding a reduction in exhaust emission levels, NGK has developed many technologies to combat these challenges. Through its NTK brand it has been increasingly involved in the development and manufacture of oxygen sensors which have a key role to play in exhaust gas after treatment. NGK Spark Plugs is now the world’s largest producer of these useful devices.
