NGK NTK 25675 Oxygen Sensor Heated Narrow-Band 4-Wire Direct Fit

The NGK (NTK) 25675 oxygen sensor, also called an O2 sensor or air/fuel ratio feedback sensor, is a direct-fit replacement. It monitors the oxygen content in the exhaust stream and sends the signal to the engine computer, which uses it to fine-tune the air/fuel mixture. A worn sensor can lead to higher fuel consumption and emissions, so replacing it helps restore engine efficiency.

Key Features:

• Switching (narrow-band) sensor with a heated element for fast light-off
• 4-wire design, 20.75 in. long, with a female oval connector and blade terminals
• M18 x 1.5 metric threads with a 7/8 in. hex size, threaded mounting
• Direct-fit design with an OE-specified, water-resistant connector and harness hardware
• 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects the sensor element from poisoning
• Dual-coated platinum interface and a thinner ceramic element give fast response times and durability
• Tested for vibration and thermal shock during OE development
• Standard replacement grade, backed by a 1-year warranty

NTK is part of the NGK family and a leading supplier of original equipment oxygen sensors. This sensor is built to match the fit, form and function of the original, which helps keep emissions low and supports good fuel economy and engine performance.
