NGK NTK 25200 Oxygen Sensor – 4-Wire Heated Downstream O2 Sensor M18x1.5

The NGK NTK 25200 oxygen sensor (O2 sensor) is an OE-type replacement. It monitors the oxygen content of the exhaust and sends that signal to the engine computer. The computer uses it to adjust the air-fuel ratio and fuel and ignition control, which helps keep the engine in its optimal operating range. NTK designs each sensor around a specific OEM application.

Key Features:

• Switching zirconia (narrow-band) sensor with a heated element for fast light-off
• Downstream position, located after the catalytic converter
• 4-wire design with a factory-style OE connector (pin terminals) for plug-in installation
• M18 x 1.5 threaded mounting, with a 7/8" (22 mm) wrench size
• Wiring harness length of approximately 22 in. (559 mm)
• Platinum-coated element and ceramic construction resist corrosion and abrasion
• Tested during manufacturing for quality and reliability
• OEM cross-reference: 392102G400

A healthy oxygen sensor supports fuel economy and lower emissions. It also lets the on-board diagnostic system detect fuel delivery or catalytic converter efficiency problems. Installation instructions are included.
