I installed these two upstream O2 sensors in my 1997 BMW 8528i. They fit and worked perfectly. The cost was about 1/2 of what the retail pricing was. I highly recommend this product.
This product came on time with no issues & soooo affordable I'll be purchasing more from this company
great product... and was delivered on time!........
Just as described for half the price. Went from 20mpg to 25mpg. 97 BMW 528I.
