    Specifications: 

    Product Material: Stainless Steel

    Product Color: Silver

    Installation Position: Upstream, Downstream
     

    Functions: 

    1. The Upstream oxygen sensor is used to Monitor Raw Exhaust Gas to Adjust Air-fuel Ratio in Real-time, i.e., it is used to Detect Whether the Exhaust Gas Exceeds the Standard.

    2. The Downstream oxygen sensor is mainly used to Detect Whether the Three-way Catalytic Converter Works Normally.

     

    Features: 

    *Corrosion-Resistant Build

    Stainless steel construction withstands exhaust heat and chemicals for long-term reliability.

    *Efficient Contaminant Blocking

    PTFE filter stops efficiency-robbing contaminants ( like soot, silicone, and grime ) from damaging the sensing element, which keeps the accuracy of the sensor and extends its lifespan.

    *Faster Response Time

    Precision zirconia element detects air-fuel changes instantly for smoother idle, sharper acceleration, and precise fuel control.

    *Optimized Engine Performance

    Maximizes fuel efficiency, reduces harmful emissions, and ensures smog test compliance. 

    *Perfect Fit Your Vehicle

    Built to strict quality control standards and with 100% factory-tested to ensure stable performance. Direct replacement, just install and drive.
