Can anyone give me a step-by-step changing both o2 sensors in 01 b5 s4? I would greatly appreciate it!


Thanks Kyle

Forgot to mention before catalytic converter

easy to get to the passenger side. Driver side you need to take of the heat sheald, and maybe pull up the intake manifold. That will give you plenty of room to work if you dont like futsing around with tight places. other then that is it straight forward, just look at it good, dont be scared!
