Product Description

Bosch advanced ceramic technology affords best-in-class performance. The ceramic element in Bosch planar type oxygen sensors is created by printing multiple layers of protective, insulating, adhesive, and conductive materials, including platinum, on several ceramic layers. These layers are pressed together and fired in a kiln and the resulting element is lightweight and incredibly hard and strong, for best-in-class performance and maximum service life.

Customer Reviews

This is a Bosch LSU 4.2
$51 shipped is the cheapest you will find this sensor anywhere. All other places sell this sensor for $70 to well over $100. This is a replacement for VWs but the sensor itself is a Bosch UEGO used by most if not all modern Wideband controllers, including Techedge, PLX, Innovate's LC-1/LM-1, Zietronix, AEM etc.

Specifically this is a Bosch LSU 4.2 UEGO (7057) sensor part 0 258 007 057.

Sensor is great for tuning
Yeah this sensor is a direct replacement for the Volks or as a WBO2 for us tuners. Great price and great product. I just don't like how if you don't know how to take care of this unit it could trash as easily.

cheap alternative for WB o2 gauges
If you own a wideband oxygen sensor gauge for your vehicle, such as the AEM UEGO or Innovate XD-16 with LC-1, this is the correct part number replacement at almost half the cost.
