NGK 24659 Oxygen Sensor 4-Wire Heated 18mm Thread O2 Sensor

The NGK (NTK) 24659 oxygen sensor, also called an O2 sensor or air/fuel ratio sensor, is an OE-identical replacement. It monitors the oxygen content of the exhaust and sends that signal to the engine computer (ECU). The ECU uses it to adjust the fuel mixture, which supports efficient combustion, lower emissions and better fuel economy.

Key Features:

• OE-identical design with a 4-wire, heated sensing circuit
• 18mm thread diameter with threaded mounting
• Wire length of about 31 inches (787mm)
• OE-type connector and attaching hardware for straightforward installation
• Dual-coated platinum element for longevity and fast response
• Pure alumina ceramic and a multi-stage element overcoat help protect against exhaust contamination
• Water-resistant connector helps guard against contamination-related failures
• Individually tested for quality and reliability
