I just received these oxygen sensors and these appear to be the OEM replacement part. These were about $25 cheaper than anyone else, they came in 2 days and I just installed them this morning in a 2000 BMW E46 323ci and noticed a big difference in MPG and the car seemed a little quicker as well. My car has 126,000 and was overdue for these - the original sensors were definitely worn. These are the pre-cat sensors by the way - E46's need post-cats as well

The price and shipping are great. I found the shell of this is thinner than the old BMW piece. So you have use different socket to remove it. Of cause, you can borrow socket kit from Autozon. The front of the two pre-cat O2 sensors is little hard to remove, WD-40 will help. The new sensor is pre-coated with anti-seize compound which is also nice. 30 minute job if you do smoothly, just beware any parts falling under engine. Just installed, difference on gas consumption is not known. Acceleration is little better.

order replacement oxygen for my BMW. The Bosch units are on and my gas mileage has improved about 5%. All is well.

Looks like a regular OEM Bosch oxygen sensor, just like one of OEM Bosch sensors I installed 100K miles ago.

I purchased these as they are OEM without the BMW part number printed on it thus adding $100 or more to the price. They installed with absolutely no problem and work perfectly. My gas mileage has increased noticeably which is quite nice. The Bimmer also feels a bit more responsive when I press the throttle.

Great product. It was the best price I could find in the internet. They are the oem o2 sensors for e39 m5. They worked great

Sensor arrived very quickly in excellent condition. Amazon.com price was well below other online retailers. Bosch has a very good reputation with replacement auto parts. I strongly recommend this product.
