    That same commitment was the driving force in the development of additional product lines such as NTK Oxygen Sensors, NTK Knock Sensors, and a variety of other sensors. Constantly developing and researching, the company also resulted in a series of world firsts for the industry, including but not limited to oxygen sensors and air-fuel sensors.

    NTK - Tech SupportNTK - F.A.Q.'sNTK - About

    Since its foundation, the company has provided its customers with A1 products and followed its philosophy of manufacturing the product where it is going to be used, which means a substantial number of NTK sensors and other products sold in the USA are made right here in America. In North America, the company is headquartered in Wixom, MI and maintains inventory and manufacturing facilities in Irvine, CA, Sissonville, WV, and Chicago, IL. Right here you can find a comprehensive collection of NTK O2 sensors, air-fuel ratio sensors, and lots of other brand's products.
