Product Details

The Bosch 11-78-7-537-984 is a premium-grade pre-catalytic converter oxygen sensor engineered to OEM standards for precise emissions monitoring and engine performance optimization. As an Original Equipment Manufacturer (OEM) part made by Bosch, this sensor delivers the reliability and accuracy needed for optimal fuel efficiency and reduced emissions.

Key Features:

  • Measures the concentration of oxygen in exhaust gases, allowing your engine to optimize the air-fuel mixture for improved efficiency and reduced emissions
  • Typical lifespan of up to 100,000 miles for long-term performance
  • Developed by Robert Bosch GmbH, a trusted name in automotive components since the late 1960s
  • Robust construction designed to perform under demanding conditions
  • Engineered as a direct OEM replacement for reliable fitment

OEM Cross-Reference Numbers: 0258017038, 17039, 11787537984

This genuine Bosch oxygen sensor helps maintain optimal engine performance by providing accurate oxygen readings to the engine control unit (ECU), enabling precise air-fuel mixture adjustments. A failing oxygen sensor can result in poor fuel economy, rough idle, illuminated check engine light, and failed emissions tests, making timely replacement essential for vehicle health.

Good prices and very good delivery timesAAAAAAAAAAAAAAAAA

Easy with great prices

Awesome prices and blazing fast shipping. I was very impressed with the level of email updates and communication communication. I would definitely order from them again! Order 17864

Don't know yet haven't put it on yet.

No comment so far.

Great

Can't complain! !

great price

thank you

Best price and super fast shipping. Only issue was that their online order status system was really far behind! The system said my order was "pending" and it had been shipped. Later it said "processing" and it was on my doorstep. Not a big deal and certainly better than the opposite (they tell you something has happened when it hasn't) and doesn't keep them from being a 5 star seller in my book.
