Sensor was a perfect match for 2006 coopers (R53). Took 15 minutes to install, a day to clear the code. Great product at a good price

Excellent Purchase!
I recommend this product, if you have a 2002-2008 MINI COOP downstream sensor needs replacing, this is it! I didnt need to reset the service engine light, it reset itself after a few miles of driving! This is my first review for this sight- Sam R (Houston, TX)
