This video shows you how to install a new upstream O2 oxygen sensor from TRQ on your 2003-2007 Infiniti G35. The Oxygen (O2) sensors help monitor the emissions system in your vehicle. They measure the amount of oxygen passing through the exhaust, which informs the computer about proper fuel/air mixture, and the condition of the catalytic converter. Over time, the sensors may fail due to contamination, or reaching the end of their service life. TRQ offers new O2 sensors made to manufacturer’s specifications.

This repair was done on a 2005 INFINITI G35 X 3.5L Sedan 4-Door AWD Automatic and the process should be similar on the following vehicles:
2003 INFINITI G35
2004 INFINITI G35
2005 INFINITI G35
2006 INFINITI G35
2007 INFINITI G35
