Overview:

The AEM Wideband O2 Sensor Bosch LSU 4.9 is a high-precision replacement sensor designed specifically for use with AEM wideband air/fuel UEGO controllers. This sensor kit includes the sensor itself, complete with an attached cable and male connector, making it an ideal upgrade or replacement for existing mounted wideband sensors. Engineered for accuracy and reliability, the sensor is factory-calibrated to provide precise air/fuel ratio (AFR) readings with an accuracy of 0.1 AFR.

Perfect for performance enthusiasts, tuners, and daily drivers alike, this sensor ensures consistent and dependable AFR monitoring without the hassle of frequent recalibration. Its robust design and compatibility with most vehicle models make it a versatile choice for maintaining optimal engine performance and tuning accuracy.

Key Features:

This Bosch LSU 4.9 wideband sensor offers advanced technology and durable construction to deliver reliable performance in demanding automotive environments.

  • Factory laser-etched, calibrated resistor embedded in the sensor’s connector body for precise sensor output.
  • Laboratory-calibrated at Bosch for exceptional accuracy within 0.1 AFR.
  • Never requires free-air calibration when used with an AEM wideband AFR controller and connector plug, simplifying maintenance.
  • High-quality sealed sensor housing with a 360-degree welded wetted area, making it virtually impervious to automotive fluids and contaminants.
  • Includes connector and pins for straightforward installation and reliable electrical connection.
  • Designed as a direct replacement sensor only, compatible with most vehicle models equipped with AEM wideband controllers.
  • Maintains sensor integrity by discouraging modification of the calibrated resistor, which would invalidate sensor output.

Construction & Design:

The sensor features a robust housing designed to withstand harsh automotive conditions, including exposure to fuel, oil, and other fluids. The 360-degree welded wetted area ensures a sealed environment that protects the sensor element for long-lasting durability. The integrated cable and male connector are engineered for secure and reliable connections with AEM wideband controllers, minimizing installation complexity and potential signal loss.

Each sensor is factory-calibrated and laser-etched with a unique resistor that matches the sensor’s characteristics, ensuring precise and consistent AFR readings without the need for additional calibration steps during installation.

Installation & Fitment:

This AEM Bosch LSU 4.9 wideband sensor is designed to fit most vehicle models that utilize AEM wideband air/fuel UEGO controllers. It serves as a direct replacement for existing wideband sensors, allowing for straightforward swap-out without modification.

No cutting, drilling, or special tuning is required when installing this sensor, provided it is used with a compatible AEM wideband controller and connector. The included connector and pins facilitate a plug-and-play installation process, making it an efficient upgrade or replacement option.

What’s Included

  • Wideband Bosch LSU 4.9 O2 sensor with attached cable
  • Male connector and pins for electrical connection
  • Replacement sensor only; mounting hardware and controllers sold separately

Ideal For:

This sensor is ideal for enthusiasts and professionals who require precise and reliable air/fuel ratio monitoring for tuning and engine management.
