BMW MINI REAR DOWNSTREAM O2 Oxygen Sensor BRAND NEW ALL MODEL ONE PRICE

Exactly the part I needed for a 2006 Mini Cooper

Great product at best possible price, much cheaper than going through the BMW service centre Note that to install this you will likely need a special socket tool with a cutout that can go over the sensor but leave space for the wire. Dont worry, $10 on Amazon / Trade Me / Ebay If you are a home mechanic dont be afraid to buy and do the replacement yourself!
