Customer Reviews

Before Catalytic Converter Oe Replacement Series Oxygen Sensor, Sold Individually 4-Wire
Good part bad customer service
When you order OE parts they fit. I purchased a kit of after market plugs and the precat burned out within a year. They also did not fully snap into the electrical connections. These worked great and plugged in perfectly. The only reason i would give this a lower rating is for the customer service i received when i received an incorrect part. They sent me a correct unit and an incorrect one. When I reached out, they did credit me the money and sent me a new one, but i needed it right away and they sent it regular shipping. They did not have the authority to overnight or at least 2 day shipping.

Great price for oxygen sensor
I got two of these for our 01 BMW 740i. It was an easy swap and they fit perfectly. The same oxygen sensor from the dealer would cost close to $200 each. These are highly recommended.

The right one
Bought one of the cheaper replacements first for my X5 and had “Low voltage” errors. Then I bought the the Bosch replacement and it solved the the problem.
