Our take on the Bosch 15741 Oxygen Sensor

The Bosch 15741 is a narrowband oxygen sensor with a 27-inch lead and Bosch's Smart Link connector, a design that lets you splice the plug to fit many vehicles instead of buying a model-specific sensor. It is a threaded 18 mm sensor for engine management on cars and trucks, including flex-fuel models. At $14.99 at eBay as of November 3, 2026, it sits at the low end of its recent price range, well under typical parts-store pricing for a Bosch sensor.

Pros
  • Low price at $14.99, among the cheapest Bosch sensors
  • Smart Link connector adapts to many factory plugs
  • 18 mm threaded body fits common O2 sensor bungs
  • No special tools needed for the install itself
  • Bosch is an original-equipment supplier for many brands
Cons
  • Narrowband output only; not for wideband or air-fuel ratio gauges
  • Splicing the connector takes time and care to seal correctly
  • One sensor only; V6 and V8 cars often need two or more
  • Wrong application is a common cause of fitment complaints

Questions and answers

Is the Bosch 15741 worth it?
At $14.99 it is one of the cheapest Bosch oxygen sensors you can buy. It makes sense if you are comfortable splicing the Smart Link connector; if you want plug-and-play, a vehicle-specific sensor costs more but installs faster.
Does it fit my car?
It is a universal-style 18 mm threaded narrowband sensor, so it fits many cars and trucks, but you must match the thread, lead length and wiring to your engine. Check your vehicle's original sensor part number before buying.
What is the Smart Link connector?
It is Bosch's splice connector that lets one sensor replace several factory plug types. You cut the old connector off and crimp the new one on, following the included instructions.
Is it a wideband sensor?
No. It has a narrowband output, which is what most older engines use for fuel trim. Cars that need a wideband air-fuel sensor require a different part.
How many sensors do I need?
This listing is one sensor. Many V6 and V8 vehicles use two or four oxygen sensors, so check how many your car has before ordering.
When is it cheapest?
The best new price was $14.99 at eBay as of November 3, 2026, with 5 stores listing it new. Prices on sensors like this move little, so compare the total with shipping across stores.
