Product Details

The Bosch 11-78-7-558-081 oxygen sensor is a premium OEM-quality heated oxygen sensor designed to monitor exhaust gas oxygen levels and provide precise air-fuel ratio feedback to your vehicle's engine control unit. This pre-catalytic converter sensor mounts in the exhaust manifold before the catalytic converter, playing a critical role in optimizing engine performance, fuel efficiency, and emissions control.

Key Features:

  • Genuine Bosch OEM quality oxygen sensor for reliable performance
  • Pre-cat sensor location (before catalytic converter)
  • Heated sensor design for faster operation and accurate readings
  • Advanced ceramic element technology for consistent performance under harsh conditions
  • Stainless steel construction for durability and corrosion resistance
  • Direct replacement for BMW part number 11787558081

Bosch invented the oxygen sensor in the late 1960s and has been the leading manufacturer of OE and aftermarket O2 sensors for over 40 years. When your oxygen sensor fails, you may experience poor fuel economy, rough idle, hesitation, or illuminated check engine light. Replacing a faulty oxygen sensor with this genuine Bosch unit restores proper engine management, reduces emissions, and helps maintain optimal fuel efficiency.

Very direct and effective. No BS.

Lowest price usually means sub-par customer service. Not the case at Autoplicity. I had questions after my item shipped, they responded promptly and professionally multiple times, and were totally willing to work with me. Very satisfying, would not hesitate to order from Autoplicity again.
