Bosch LSU ADV is the latest version of oxygen (O2) sensor from Bosch, the one after LSU4.9.

While most of Wideband controller manufacturers are still using the LSU4.2 or the LSU4.9 sensors for their products, we have taken the liberty and have taken the lead on the most advanced Wideband control system with LSU ADV sensors.

The Bosch LSU ADV has these advantages over the LSU 4.9 :

  • Higher operating temperature, making it more robust with heat.
  • Faster heating response speed of only 5 seconds.
  • Stronger thermal shock resistance.
  • Triple layer protection tube
