Features & Product Details

RallySport Direct proudly carries a great selection of quality performance products brought to you by AEM. 

Here, you are looking at the Bosch LSU 4.9 Wide-Band O2 Sensor. This is the replacement sensor for the AEM UEGO Wideband Gauge. Now you can purchase the sensor separately without having to purchase an entire new gauge. Sometimes leaded race fuels with long-term use can have an effect on these sensors, and these are wear and tear items just like anything else. Whatever the reason may be, rest assured this sensor is available separately.

    • Q: How do I tell the difference between the 4.9 and 4.2  mhvone010063 years ago

      How do I tell the difference between the 4.9 and 4.2
    • Q: LSU 4.9 vs 4.2  z.p578516 years ago

      I have an AEM UEGO wideband controller currently hooked up to the OEM Rear O2 sensor (prior install, not my work), and am looking to replace it with their Wideband O2 sensor. Is there any difference in the harness specifically between the LSU 4.2 vs the 4.9? Does it matter (apart from the 4.9's better life expectancy) which one I get for my existing UEGO Controller? Thanks!

        A:  The connectors for the 4.2 and 4.9 sensors are different, and they are not interchangeable.
