NGK Hyundai Santa Fe 2015-2010 Direct Fit 5-Wire Wideband A/F Sensor

When your check engine light comes on and you suspect an issue with your air-fuel mixture, a faulty oxygen sensor could be the culprit. This NGK 5-wire wideband Air-Fuel Ratio (A/F) sensor is designed to help your vehicle's computer precisely control fuel delivery for optimal engine performance, better gas mileage, and reduced emissions. It fits a wide range of Hyundai and Kia vehicles, including models like the Hyundai Santa Fe, Sonata, and Kia Optima.

Unlike older switching sensors that just tell the computer if the mix is rich or lean, this wideband sensor provides a linear output. This means the engine control unit (ECU) gets a much more detailed picture of the air-fuel ratio, allowing for continuous and accurate adjustments. NGK, a major OEM supplier, builds these sensors with an advanced ceramic element that resists contamination and poisoning, helping to ensure a long service life. The plasma jet and deposit trap overcoat further protect the sensor from contaminants.
