NGK NTK 25754 OE Type Oxygen Sensor Heated Narrow Band 4-Wire O2 Sensor

The NGK NTK 25754 OE type oxygen sensor (also called an O2 sensor or lambda sensor) is a direct-fit replacement made to match the form, fit and function of the original equipment sensor. It reads the oxygen content of the exhaust and sends that feedback to the engine control unit (ECU). The ECU uses it to manage the air-fuel ratio, which supports engine performance, fuel efficiency and low emissions.

Key Features:

• Heated, narrow band oxygen sensor design
• Advanced ceramic sensor element with a 3-stage contaminant-resistant overcoat to protect against element poisoning
• Dual-coated platinum interface and a thinner ceramic element for fast light-off and response times
• Pre-attached 20 in. wiring harness with an OE-specified, water-resistant oval connector
• Female connector with 4 blade terminals

Specifications:

• Thread size: M18 x 1.5 (18 mm thread diameter)
• Wrench size: 7/8 in. (22 mm) hex
• Mounting type: Threaded
• Wiring harness length: 20 in.
• Grade: Standard replacement

NTK is a leading supplier of original equipment oxygen sensors. A failing sensor can increase fuel consumption and emissions, so replacing it helps restore proper engine management.
