Bosch LSU4.2 5-wire, wide-band O2 sensor.
This sensor is used with all the Innovate air to fuel ratio meter/controller products such as the Innovate MTX-L, LC-2, LM-2, LC-1 and LM-1 up to approximately April 2015 at which point the sensors were changed over to LSU4.9 sensors.
A wide-band controller is used in conjunction with this sensor. i.e the sensor cannot be used by itself.
Features an OEM-style harness, meaning that no crimping or wiring is required – plugs straight into your existing Innovate wide-band controller.
Double laser-welded stainless steel body.
M18 x 1.5 Thread.
