Hi all.
i have 2 brand new O2 sensors for a 2.8 engine(atq).

I'm just wondering that if i can put thess o2 sensors to my 02 a6 3.0 quattro (avk). Ecstuning only has a universal o2 sensor for the 3.0 engine. maybe the 2.8 sensor works?

Audi C5 A6 Quattro V6 2.8L > Search > Oxygen Sensor > ES#1574 Upstream Oxygen Sensor - 078906265M

 

Anyone?

 

ECS has proper o2 sensor for your car.

ECS o2 sensor 3.0

Anyways Amazon is cheaper.

 

i mean i already have 2 o2 sensors for 2.8.
i would use them for 3.0 if it's ok...

 

Connectors would not work. As for the actual sensor itself, I don't know.
