NGK 25614 NTK Oxygen Sensor O2 Sensor Heated 4-Wire Direct Fit

The NGK 25614 oxygen sensor (also called an O2 sensor or lambda sensor) is an OE-identical replacement from NTK, NGK's oxygen sensor brand. It monitors oxygen levels in the exhaust stream and sends that data to the engine computer. The computer uses it to keep the air/fuel mixture accurate, which supports fuel economy, emissions control and catalytic converter life.

Key Features:

• Heated sensor design that reaches operating temperature quickly, which helps lower emissions and improve fuel economy
• 4-wire configuration with an OE-type connector
• Threaded mounting with an 18mm thread diameter
• Wire length of 750mm (29.5 in)
• Dual-coated platinum element for longevity and fast response time
• Built to the same fit, form and function as the original equipment sensor, including wire length, protective sleeve, grommets and clips
• Factory-fitted OE connector and attaching hardware for straightforward installation

A worn or failing oxygen sensor can cause higher fuel consumption, increased emissions and poor engine performance. Replacing it with a sensor built to OE specifications helps restore proper closed-loop engine control.
