I've been using the Walker 250 oxygen sensor for a couple of weeks in my 2003 Audi A4 Quattro, and it's been fantastic. The 4-wire setup made it easy to connect, and the performance is noticeable. No more check engine light, and the car feels peppy again!

Decent performance but installation was tricky
The Walker 250 sensor works well, but the installation instructions could've been clearer. It took me longer than expected to get it in, plus my hands barely fit in that tight space. Once it was in, the sensor has been working great for about a month now!

Arrived damaged, but works fine
I was disappointed that the Walker 250 oxygen sensor arrived with a dent in the casing. Luckily, it still works after installation in my 2002 A4 Quattro. I just wish the packaging was better because I almost sent it back!

Fits perfectly in my Audi
I installed the Walker 250 oxygen sensor in my 2004 Audi A4 Quattro, and it fit right in with no issues. The car is running smoother now, and I’ve noticed better fuel efficiency. Definitely a solid replacement for the stock sensor!
