Bosch Oxygen Sensor P/N:13115
Bosch 13524 oxygen sensor for the 1996-1997 Audi A4 V6 2.8L and other vehicles reports the air-fuel ratio to the ECU. This Bosch O2 sensor supports stable combustion control and helps reduce emissions.
A rough idle, poorer fuel economy or a check engine light can mean the oxygen sensor is worn, though a vacuum leak or a failing ignition coil can show up the same way, so trace the cause before you replace it.
It fits the 1996-1997 Audi A4 V6 2.8L and the 1996-1997 Audi A4 Quattro V6 2.8L, which take two sensors; this listing is one.
