Bosch Wide-band A/F Oxygen Sensor

Bosch Wideband Air/Fuel ratio sensors utilize a more sophisticated sensing element that enables them to produce a precise output in proportion to the air/fuel ratio. As a result, a wideband A/F sensor measures exhaust gas oxygen accurately from as rich as 9.0:1 to as lean as free air. The use of the Wideband A/F sensors is growing rapidly as original equipment in vehicles and in high-performance specialty markets.
  • A protection tube ensures 100% accurate sensor performance to provide for proper engine management
  • The double laser-welded stainless steel body is totally submersible to seal tight and protect against contamination for a long service life

Rated 5 out of 5 by 5 reviewers.
Rated 5 out of 5 by PERFECT FIT AND FUNCTION SEEMS TO BE WORKING WELL. i HAVE NO CHECK ENGINE LIGHT ON ANYMORE. August 29, 2016
Rated 5 out of 5 by TRUE Replacement quality parts. Heat shielded cable. Hooks up to the original part easily, once the wire is threaded. Be CERTAIN to specify between LEFT and RIGHT, as the connections are different. September 9, 2015
Rated 5 out of 5 by Great quality a very decent price Replacing the old, faulty o2 sensor on my 2004 SENTRA solved the very poor mileage I was getting. Plus no more bothersome SES light anymore! It's very easy, and some homework helped me determine the o2 sensor was indeed the problem. I ordered via the internet-store pick up and the part was in my hands in about 30 minutes, with a sizable discount, to boot. This sensor is a quality buy from a prestigious manufacturer (OEM in many applications) for a fraction of the price of the actual OEM part. Win,win,win for me. August 20, 2015
Rated 5 out of 5 by This product fit just like a factory replacement. This product fit just like a factory replacement at half the price. October 22, 2013
Rated 5 out of 5 by Replacement O2 sensor Excellent direct replacement with anti-seize compound coating threads for easy installation. July 31, 2013
