NGK Spark Plug

NGK spark plugs are globally recognized ignition components produced by Niterra (formerly known as NGK Spark Plug Co., Ltd.). Founded in 1936 in Nagoya, Japan, the brand has grown to be a market leader in internal combustion engine technology.

Manufacturing is distributed across several global locations to meet regional demands, including major facilities in Japan, Brazil, the United States, and Thailand. In 2023, the parent company rebranded from 'NGK Spark Plug' to 'Niterra' to reflect a broader business focus beyond ceramic parts and spark plugs, though the NGK brand remains the primary identity for its automotive products. The brand is a staple in both consumer automotive maintenance and professional motorsports including Formula 1.
