Bosh LSU 4.2 Wideband Lambda sensor
This sensor can be used on engines controlled by an AEM Infnity ECU without needing an external controller. It also works with some of the AEM Wideband contollers and guages as well.
Not to be used on AEM X-series Wideband controllers that are designed to operate using a Bosch LSU 4.9 Lambda sensor.
Our kit includes 1 new Lambda sensor, a stainless sensor bung, and the latching connector kit for people who are building a new wiring harness to work with this sensor.
