The Bosch LSU 4 (or 4.x to cover all variants) sensor is a pump cell sensor (the NTK L1H1, or UEGO sensor family is similar). The sensor requires a bung with an 18 mm diameter hole with 1.5 threads/mm pitch (M18x1.5) and this is one of the standard lambda sensor & spark-plug base sizes).
This link gives a technical overview of how 5 wire pump cell sensors work.
The image shown at left is a cut-away of an actual LSU 4.0 sensor showing the pump cell. The pump cell is the ceramic "rectangle", and it's just over 4 mm across (ie. it's small). The image at right is a cross section drawing of a complete LSU sensor with the red circle indicating where the pump cell is located.
We have more technical information here on the Bosch 0 258 006 066 LSU 4.0 sensor. Note that some documents describe the 6066 as an LSU 4.2 (including some Bosch documentation) rather than a 4.0 - If Bosch can't decide we don't really care, but the 6066 "family" and the "7057" family are electro-chemically different.
Tech Edge has used the following LSU sensors with the WBo2 unit. The differences are in the connector and the calibration values required.

A number of vehicle manufacturers currently use a Bosch LSU 4 wideband sensor on their production vehicles. Feel free to contact us and add to the following list. Where there are multiple part number, like 057/058 they refer to the same sensor with longer or shorter leads. A sensor in this list doesn't imply the Tech Edge WBo2 unit supports it. See also www.forparts.com for another list of vehicles using Bosch wideband sensors.
