NGK 25160 Oxygen Sensor Narrow-Band Heated 4-Wire Direct Fit O2 Sensor

The NGK (NTK) 25160 oxygen sensor, also called an O2 sensor or lambda sensor, is a heated, narrow-band, direct-fit replacement sensor. It gives the engine computer continuous closed-loop feedback on exhaust oxygen content. The computer uses that feedback to control the air-fuel ratio, which supports engine performance, fuel efficiency and lower emissions. It also helps the OBDII system flag fuel delivery or catalytic converter problems.

Key Features:

• Dual-coated platinum sensing element for longevity and fast response
• Integrated heater brings the sensor to operating temperature quickly, for faster closed-loop activation and reduced cold-start emissions
• Premium technical ceramic sensing element
• Corrosion-resistant housing protects the ceramic element from silicone and lead poisoning
• Porous PTFE filter lets atmospheric oxygen in while keeping out water and engine contaminants
• OE-specified, water-resistant connector and harness hardware for easy installation
• Tested during manufacture, including vibration and thermal shock testing

Specifications:

• Sensor type: narrow-band (switching zirconia), heated
• Wires: 4
• Thread: M18 x 1.5
• Hex / wrench size: 7/8 in. (22 mm)
• Mounting: threaded
• Wiring harness length: approx. 24.75 in.
• Grade: standard replacement

Replacing a worn or failed oxygen sensor helps protect the catalytic converter. It also helps restore fuel economy and emissions performance.
