Product Details

The Bosch 13847 Oxygen Sensor delivers precise air-fuel ratio monitoring for optimal engine performance and emissions control. This premium 4-wire heated oxygen sensor is designed as a direct OE replacement, ensuring proper fit and function without cutting or splicing.

Key Features:

  • Premium ceramic technology incorporating Zirconium or Titania and Yttrium for superior protection against mechanical and thermal shock
  • Patented catalytically activated fine particle filter prevents contamination and ensures precise voltage signals to the engine control computer
  • Dual-filter design provides double protection against exhaust gas contamination for extended sensor life
  • 4-wire heated design for faster activation and accurate readings in all operating conditions
  • 15.8-inch wire harness with OE-style silicone boots for secure, factory-quality installation
  • Direct plug-in connector eliminates the need for wire splicing or modifications
  • Mounts before the catalytic converter to monitor exhaust gases and prevent premature converter failure

Bosch oxygen sensors are rigorously tested to deliver precise performance, helping reduce emissions while optimizing fuel economy. The advanced filter technology and robust ceramic construction ensure reliable operation and longevity, even in harsh exhaust environments.

Specifications: 4-wire heated sensor | 15.8-inch wire length | Before catalytic converter location | Sold individually

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

Autoplicity was quick and easy to order from. I found just what I was looking for in absolutely no time at all, plus it was shipped extremely quickly. I would definitely order from this site/company again.<br><br>Thanks!

excellent ship time and exceptional pricing deffinatly will buy from here again

So far so good

Fast shipping, product was excellent .

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
