NGK Subaru Forester 1999-1998 Direct Fit Oxygen Sensor

NGK is known worldwide as a top supplier of original equipment oxygen sensors, and this direct-fit sensor for your 1996-1999 Subaru Legacy is built to that same standard. Oxygen sensors are a key part of your vehicle's diagnostic system, working to keep the engine running at its best. They provide constant feedback to the engine control unit (ECU) to manage the air-fuel mixture, which helps maximize fuel economy and reduce harmful emissions. This sensor also alerts the OBDII system to potential issues with fuel delivery or the catalytic converter.

The advanced ceramic element inside this sensor features a 3-stage contaminant-resistant plasma jet and deposit trap. This design helps protect the sensor from poisoning, ensuring it can accurately monitor exhaust gases over time. NTK, a ceramics company at its core, controls the entire manufacturing process from raw materials to the finished product, ensuring consistent performance and reliability.
