View Full Version : I30 O2 sensor

hey, I just bought an 01 Inifinti and the ses light came on which I had coded and it is the O2 sensor. My question is how hard is this to replace? I'd like to do it myself.

Depends on which one - the rear one is not bad, front is harder. Borrow an O2 sensor socket/wrench from an auto parts place first.
