Product Details

The Bosch 17202 is a premium wideband air/fuel ratio sensor that precisely measures the amount of oxygen in the exhaust rather than just switching between rich and lean conditions. Bosch is the world's leading supplier and original equipment manufacturer of oxygen sensors, having invented the automotive oxygen sensor.

Key Features:

  • Advanced wideband sensing element provides a signal proportional to the amount of oxygen in the exhaust for precise engine management
  • Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions
  • Fast-acting heater allows the sensor to reach operating temperature within seconds for optimum performance
  • True direct-fit OE connectors and harness with threads pre-coated with anti-seize compound for easy installation
  • 100% factory tested for full functionality, ensuring rigorous quality and performance standards
  • 5-wire design, heated, 42.91 inches long for exact OE fitment

This sensor cross-references to OEM part numbers 11 78 7 557 758 and 11 78 7 586 693. The wideband design enables more accurate air-fuel mixture monitoring compared to standard oxygen sensors, helping maintain optimal engine performance, fuel efficiency, and emissions control.

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Impressed with selection and price. Saved over traditional e-tailers and they shipped within 24 hours. Excited to recommend AUTOPLICITY.

Ordered a Simpson helmet on Monday afternoon, received tracking on Monday evening and will have the product on Wednesday! Quick service! Also would like to mention that the price was the lowest of anywhere I looked up.
