Product Details

The Bosch 11-78-7-589-121 is an OEM-quality upstream oxygen sensor designed specifically for BMW vehicles equipped with N20 and N26 2.0L turbocharged engines. Installed before the catalytic converter in the exhaust pipe, this pre-catalytic O2 sensor measures oxygen levels in the exhaust gases and provides vital data to the engine control unit (ECU) to optimize the air-fuel mixture, improving fuel efficiency and reducing emissions.

Key Features:

  • Utilizes a mix of zirconium and yttrium oxides to form a tough ceramic base that withstands intense stress for best-in-class performance and maximum service life
  • Patented Platinum Power Grid for precise oxygen measurement
  • Direct fit for easy installation with OE-style connectors and wire lengths
  • No cutting or splicing required—plugs directly into factory connector
  • 100% functionally tested during manufacturing to ensure quality and reliability

Replacing a malfunctioning oxygen sensor can significantly enhance vehicle performance, as symptoms of a failing sensor include poor fuel economy, rough engine idle, and increased emissions. This genuine Bosch sensor ensures your BMW maintains optimal performance and passes emissions testing with confidence.

We ordered a Thule 9003 Raceway 2-bike rack for my 2011 Honda Civic and it arrived in 2 days. We were very surprised at the fast service. I also had my thoughts that it wouldn't be the exact name brand product I was looking for and a off brand but the same type and I have to say it was exactly the product I wanted. The price was great too. I researched several dealers and Autoplicity was the lowest price at $100 less than others and that included the shipping. I would definitely order from Autoplicity again.

all good so far

Good picture and description!
