NTK 25268 OE-Style Replacement Oxygen Sensor

The NTK 25268 is a direct-fit OE-style replacement oxygen sensor (O2 sensor / lambda sensor) engineered to restore proper air-fuel ratio management and exhaust monitoring to your vehicle. NTK is the world's largest supplier and manufacturer of original equipment oxygen sensors, bringing the same OEM-grade technology to the aftermarket replacement market.

Oxygen sensors play a critical role in your vehicle's on-board diagnostic (OBD) system by continuously measuring residual oxygen levels in the exhaust stream and reporting that data back to the engine control unit (ECU). This closed-loop feedback allows the ECU to precisely regulate the air-fuel mixture, maximizing fuel efficiency, reducing harmful emissions, and protecting the catalytic converter from premature failure.

Key Features:

• OEM Quality: Meets or exceeds original equipment specifications for fit, form, and function
• Advanced Ceramic Sensor Element: Features a dual-coated platinum interface and 3-stage contaminant-resistant plasma jet and deposit trap overcoat to protect against element poisoning
• Fast Light-Off Performance: Thinner ceramic element and superior platinum interface deliver the quickest response and light-off times for faster closed-loop operation
• OE-Specified Connector & Hardware: Equipped with water-resistant, OEM-specified connector and harness accessory hardware for straightforward, no-modification installation
• Extensive Testing: Each sensor undergoes vibration and thermal shock testing during OE development, with individual testing during manufacturing to guarantee quality and reliability
• Upgraded OE Technology: Specifically engineered for the aftermarket based on OE expertise to reduce common OE failure modes and enhance durability

Replacing a failed oxygen sensor with the NTK 25268 can help restore fuel economy, lower exhaust emissions, eliminate related diagnostic trouble codes (DTCs), and extend the service life of the catalytic converter.
