This genuine Bosch LSU 4.9 wideband sensor replaces a worn sensor on AEM controllers built around the 4.9-generation sensor, including PN 30-0300, 30-0334, 30-0310, and 30-4110. It ships with its cable and connector attached and is factory-calibrated to 0.1 AFR, so it never needs free-air calibration when used with a compatible AEM controller.

Key Features

  • Bosch LSU 4.9 sensor with attached cable and connector
  • Laser-etched, factory-calibrated resistor in the connector body
  • Sealed, 360-degree welded housing resists automotive fluids
