NGK NTK Home
Domestic & Import OE Legacy
NGK is the largest manufacturer of OE spark plugs and OE oxygen sensors in the world. With over 80 years of mobility expertise, we are driven by extreme dedication to performance and quality.
High ignitability tip designs.
Our high ignitability tip designs provide maximized combustion efficiency that result in a complete fuel burn, a quicker throttle response, smoother idling, and better cold starts.
Coils and plugs, a dynamic duo.
Spark plugs don’t run alone. So we applied our expertise in ignition technology to make a better coil. Engineered to OE durability and performance, we continue to test and validate for easier installation and better performance.
Over 99% coverage.
NTK offers over 1,350 part numbers for oxygen sensors, covering over 99% of vehicles in operation, including a variety of domestic, European and Asian applications. Offering both switching and wide band technologies, NTK is continuously developing sensor technologies to work with new advanced vehicle computer components.
Our expertise in sensor technology.
Our OE heritage in oxygen sensors allows us to deliver aftermarket oxygen sensors from the same assembly lines as our OE products. Our expertise in sensor technology is applied to the NTK Premium Technical Sensor program, featuring coverage for both import and domestic vehicles. NTK technical sensor products are 100% tested to meet and or exceed OE specifications.
