This product is a high-performance aftermarket sensor compatible with Bosch LSU4.9 (genuine part number: 0 258 017 025) and DENSO 234-5114, 234-5116, 234-5137.
In engine control, the air-fuel ratio sensor is a critical component that optimizes the balance of fuel economy, power, and emissions.
Specifically, this LSU4.9 type is classified as a "wideband sensor," offering higher accuracy than conventional narrowband sensors and enabling real-time fuel control.
However, the air-fuel ratio sensor is constantly exposed to high-temperature exhaust gases, and performance degradation or erroneous detection may occur due to aging after approximately 100,000 km of driving.
Are you experiencing these symptoms? (1) Fuel economy has suddenly worsened (2) Idling is unstable (3) Engine warning light (check lamp) is illuminated (4) Exhaust gas smells or fails vehicle inspection If you have these symptoms, the cause may be deterioration or failure of the air-fuel ratio sensor.
This product is a cost-effective compatible sensor that helps improve or prevent such malfunctions.
