NGK 24688 Direct Fit Oxygen Sensor O2 Sensor 4-Wire Heated 18mm

The NGK 24688 oxygen sensor (also called an O2 sensor or NTK oxygen sensor) is a direct-fit replacement designed to match the fit, form and function of the original equipment sensor. It gives the engine computer constant feedback on exhaust oxygen content. The computer uses this to regulate the air-fuel ratio, which supports fuel economy, engine performance and low emissions.

Key Features:

• Dual-coated platinum element for longer life and fast response time
• Heated sensor design heats up quickly, which helps cut emissions and improve fuel economy
• 4-wire design with an OE-type connector for plug-in installation
• Threaded mounting with an 18mm thread diameter
• Wire length of 546mm (21.5 in)
• Alumina ceramic construction
• OEM specified connector and attaching hardware
• Cross-references to OEM numbers 1588A050, 1588A051, 1588A112, MN163468, MN163469, MN163470 and MN191125

A worn oxygen sensor can cause poor fuel economy, a rough-running engine and higher emissions. It can also trigger a check engine light. Replacing it with a quality NGK/NTK sensor helps restore proper closed-loop fuel control.
