Product Description
Bosch 17025 LSU 4.9 Wideband Oxygen O2 Sensor for Holley and AEM Systems
39-Inch Sensor with D-Shaped LSU 4.9 Electrical Connector
Replace the wideband oxygen sensor in a compatible Holley or AEM system with Bosch part number 17025. This LSU 4.9 wideband O2 sensor is a popular replacement for Holley Terminator X and Sniper systems and fits AEM wideband kits 30-0300, 30-0310 and 30-4110.
Measuring 39 inches from the sensor tip to the end of the electrical connector, Bosch 17025 uses the D-shaped connector associated with LSU 4.9 applications. It will not interchange with LSU 4.2 sensors using a rectangular connector and is not compatible with Holley Dominator, Holley HP or AEM 30-4100 systems.
Key Features & Benefits
- Bosch 17025 Wideband O2 Sensor: Provides the exact Bosch part-number identification needed when replacing a compatible wideband oxygen sensor. Its LSU 4.9 configuration makes it suitable for the specifically listed Holley and AEM engine-management and wideband systems.
- Holley Terminator X and Sniper Compatibility: Commonly used as a replacement wideband oxygen sensor for compatible Holley Terminator X and Sniper systems. This defined compatibility helps distinguish Bosch 17025 from sensors intended for Holley Dominator or HP systems.
- Fits Select AEM Wideband Kits: Compatible with AEM wideband kit part numbers 30-0300, 30-0310 and 30-4110. The supplied kit-number coverage provides a clear reference when selecting a replacement sensor for one of these supported AEM systems.
- 39-Inch Overall Sensor Length: Measures 39 inches from the tip of the oxygen sensor to the end of its electrical connector. This exact measurement helps identify the physical configuration supplied with Bosch part number 17025.
- D-Shaped LSU 4.9 Connector: Uses the D-shaped electrical connector associated with LSU 4.9-style sensors. The connector shape provides an important visual distinction from LSU 4.2 sensors, which use a rectangular connector and are not interchangeable with this Bosch sensor.
Notes
- Does not fit Holley Dominator, Holley HP, AEM 30-4100 or applications requiring an LSU 4.2 sensor.
- Due to the nature of their use, wideband oxygen sensors are sold without a warranty.
