NGK has gained its worldwide leading position in spark plugs and lambda sensors with continuous effort and technical expertise. And with a clear commitment to the highest possible quality.

Glow plug production in Komaki, Japan

The plant is equipped with the most modern production technology and produces in accordance with the latest international quality standards. Moreover, at the end of the production, just before packing, a fully-automated functional test of every single glow plug takes place. In doing so, consistent high quality can be guaranteed at all times.

Consistent high quality in Ratingen, as well

The sales organisation, logistics and the technical centre meet the highest demands. For example, NGK Spark Plug Europe uses quality management certified in accordance with ISO 9001:2008, which is regularly put through the paces by TÜV Rheinland.

The result is a long list of distinctions - awarded by both original equipment customers and partners in the aftermarket.
