Product Details

The Bosch 11-78-7-514-926 (Bosch part number 15680) is a premium original equipment oxygen sensor designed for BMW vehicles equipped with M54 and M56 engines. This post-catalyst O2 sensor is positioned in the rear (downstream) location of the exhaust manifold for cylinders 1-3, monitoring exhaust oxygen concentration to optimize air-fuel mixture and engine performance.

Key Features:

  • OEM quality from Bosch, the original inventor of automotive oxygen sensors
  • Double laser-welded stainless steel body provides complete submersibility and protection against exhaust emissions
  • Fast-acting heater reaches operating temperature within seconds for optimal performance
  • 100% factory tested for full functionality to ensure quality and reliability
  • Direct-fit design with OE connector for straightforward installation
  • Helps improve fuel economy while reducing harmful emissions

Oxygen sensors play a critical role in modern engine management systems by measuring unburned fuel in the exhaust stream. This data allows the engine control unit to adjust fuel mapping for better emissions control and fuel efficiency. A failing oxygen sensor can result in poor fuel economy, reduced performance, and potential check engine light illumination. Bosch oxygen sensors are engineered with decades of sensor technology expertise to deliver long-lasting, superior performance you can trust.

Very fast shipping plus I saved a ton of money on the same lift kit I would have purchased locally!

Great !!!!!!

It was very easy. I am looking forward to seeing it. It's for my granddaughters truck.

Wicked fast shipping! 3 days from California to Key West, Florida! We are amazed by this super fast service. Part is brand new and fits perfectly! Will use you again and HIGHLY recommend you!

their write up about the product was slightly miss leading being that it was saying that the part went to the wrong car. But the part number said it was for a different car. <br><br>But hands down they had the best price and so far seems to be a great company. I would purchase from again. It would be ideal if they offered more in the sports compact area though.

Very happy with my order with Autoplicity. Hands down the best price on brake pads that I could find. One set took a little longer to arrive since the manufacturer was to send them out, but a call to customer service yielded an explanation and a few days later they were on my door step.

quick, easy, good price
