NGK 24293 Oxygen Sensor 4-Wire Heated Direct Fit 18mm Thread O2 Sensor

The NGK 24293 oxygen sensor (also called an O2 sensor or air/fuel ratio sensor) is a direct-fit, OE-type replacement. It monitors the oxygen content of the exhaust and sends voltage signals to the engine control unit. The ECU uses those signals to adjust the air/fuel mixture for efficient combustion, lower emissions and good drivability.

Key Features:

• Direct-fit design built to OE standards and specifications
• Dual-coated platinum element for longevity and fast response time
• Sensing element made with NTK technical ceramics and an integrated heater, for quick light-off and closed-loop activation
• Corrosion-resistant housing that protects the ceramic element from silicone and lead poisoning
• Porous PTFE filter lets atmospheric oxygen in and keeps water and contaminants out
• Water-resistant, factory-fitted OE-type connector for plug-and-play installation
• Individually tested during manufacture for quality and reliability

Specifications:

• Type: Heated, direct fit
• Number of wires: 4
• Thread diameter: 18 mm
• Hex size: 22 mm
• Wire harness length: 9.5 in. (241 mm)
• Mounting: Threaded
• Upper temperature rating: 1472°F

A worn or failed oxygen sensor can cause higher fuel consumption, poor drivability, a check-engine light and a failed emissions test. A new sensor helps restore fuel economy and engine efficiency, lowers emissions and protects the catalytic converter.
