NGK 23527 Oxygen Sensor Heated Narrow Band 4-Wire 18mm Thread

The NGK (NTK) 23527 oxygen sensor, also called an O2 sensor or exhaust gas oxygen sensor, measures the oxygen in your exhaust. It sends that data to the engine computer, which uses it to manage the air-fuel mixture. This is a direct-fit, OE-style replacement for emissions control and fuel economy.

Key Features:

• Heated, narrow-band oxygen sensor design for faster response
• 4-wire configuration with a rectangular female connector and pin terminals
• Threaded mounting with an M18-1.5 (18 mm) thread
• Wire length of about 18 in. (460 mm)
• Factory-fitted OE-specified, water-resistant connector for easy installation
• Ceramic sensor element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat to protect against element poisoning
• Dual-coated platinum interface and a thinner ceramic element for fast light-off and response times
• Made from metal, plastic and rubber
