** This listing is for Bosch LSU 4.9 sensor only **

Bosch Compatible LSU 4.9 Wideband Oxygen Sensor


These Bosch Compatible Sensors are supplied by DIYEFI who calibrate the sensor and brand the casing with their logo.

This is a custom sensor by DIY EFI which is made to Bosch specification with the CORRECT value calibration resistor fitted.
( Whilst technically not a Bosch part it is correct in operation unlike the cheaper clones which do not have the correct resistors fitted )


Used with our own CFI Classic Fuel injection system but can also be used with many other systems

It is with the help of this clever piece of kit that our Classic Fuel Injection system self learns when the vehicle is driven, so whilst not essential to our CFI kits it is highly recommended.
