While conventional switching oxygen sensors only switch rich or lean, wideband oxygen (or Air-Fuel Ratio) sensors produce a linear output signal that allows the ECU determine exactly how rich or lean an engine is running and make continuous and precise adjustments of the air-fuel mixture to stay closest to stoichiometric, providing the best possible combustion and fewest emissions. A ceramics company at our core, NTK uses state-of-the art technology enabling complete control of the ceramics used in our wideband oxygen sensors from raw material to finished product. Trust The Sensor Specialist for full-line market support and OE application technology.

Product Features:
  • OEM QUALITY: NTK is the world’s largest supplier of original equipment oxygen sensors with renowned quality that meets or exceeds OEM specifications
  • PRODUCT ENGINEERING: Based on OE expertise, but specifically engineered for the aftermarket, NTK Oxygen Sensors offer superior OE fit, form, function
  • OE TECHNOLOGY: Upgraded to the latest OE technologies, NTK Oxygen Sensors are designed to reduce OE failures, enhance durability and performance
  • EXTENSIVE TESTING: OE development includes vibration and thermal shock testing. Testing during manufacturing guarantees quality and reliability
  • EASY INSTALLATION: NTK Oxygen Sensors are equipped with OE specified, water-resistant connectors and harness accessory hardware for easy installation
  • ADVANCED CERAMIC SENSOR ELEMENT: 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects against element poisoning
