Bump . . .
Brand new Bosch Oxygen Sensor. I bought it for a 1996 Audi A4 2.8, sold the car therefore I no longer need it. It was never installed on the vehicle. Upon further research it looks like it will fit 1996-1997 Audi A4 2.8 SOHC. This oxygen sensor is before the catalytic converter. You should verify before buying. Go online. Bosch Part #13524. Price is $85 shipped in the lower 48. Pm for more details or questions.
