Rated 5 out of 5 by Great price on a Key Component!& The Bosch Oxygen Sensor is easy to install and was the best price out of all the other Parts a Expeditors out there. Gus and Anna at this Costa Mesa,CA store are the people who keep me coming back. They offer the right part, at the right price, at the right time!!!

Rated 5 out of 5 by this part fit perfectly this part was in stock, near my home and was available immediately. there was a lower price on line but would take a few days to arrive. this was the exact replacement for the original and it fit fine and works fine. the extra money was worth it for the instant availability. November 15, 2016
Rated 3 out of 5 by The item was hard to install Hard to install from under the car because you had to put it together, laying down on the ground. November 13, 2016
Rated 5 out of 5 by Worked and fit perfectly I had to replace bank 1 O2 sensor and this replacement from Pepboys worked just fine for my 2011 Toyota Rav 4 V6. The check engine and other lights were gone after installation. October 31, 2016

Rated 5 out of 5 by Perfect Love pep boys but what a gigantic pain for a Canadian to get through rewards sign up and checkout. It's easier to buy a gun than car parts. October 25, 2016

Rated 5 out of 5 by Solved the problem Had a check engine light on my 2003 Jeep Liberty. Dad to go to a muffler shop to install because the old unit was badly corroded to the exhaust. Solved the problem.. Great price compared to other sensors available October 1, 2016
Rated 5 out of 5 by everything was oki couldn't be better September 20, 2016
Rated 5 out of 5 by Worked as purchased! I had to replace all 4 O2 Sensors on my car, from what I read would save me fuel (up to 100.00/year) and would save me from problems down the road with the engine spitting out harmful & ruining my 2 catalytic converters. It ran well before, and it runs like a top now, idles better, shifts better, even coasts and downshifts smoother. September 18, 2016

Rated 1 out of 5 by Made things worse OEM sensor was damaged when replacing my catalytic converter. Purchase this unit and made my engine perform very poorly. Quick look on line and discovered that this is common with Bosch sensors. Replaced it with one from NGK. My Jeep is running like new again. If you have a Jeep 4.0 engine, stay away from this sensor, go with an NGK version. September 11, 2016
Rated 5 out of 5 by GREAT PRODUCT Great product September 10, 2016
Rated 5 out of 5 by Lifetime warranty! I've replaced the O2 sensors both a couple times already, with only 140,000 miles on my car. Pepboys is the only seller I've found to offer a lifetime warranty on an O2 sensor, and at a very reasonable price. September 9, 2016

Rated 1 out of 5 by It wasn't a good replacement for the motorcraft one Kept giving me errors on car computer so had to go back and use motorcraft one. Computer kept getting 'out of range values' from Bosch sensor August 21, 2016
Rated 5 out of 5 by good product Easy to install and does what it is supposed to do. August 18, 2016
Rated 5 out of 5 by Right fit connection. Easy to install. August 11, 2016
Rated 1 out of 5 by so so Denso and NGK are the preferred choices due to quality - but were not available for my vehicle - August 4, 2016
Rated 5 out of 5 by Economical solution This universal fit sensor is simple to install. Pay attention to the step-by-step instructions with diagrams. There's a video online if reading is a problem. The electrical connections to the wiring harness need to be done right, but it's explained in detail and no soldering necessary. You do need a special socket wrench to remove the old sensor and screw this one into the pipe. It even comes with anti-seize compound on the threads. It started working as soon as it was connected and is working well a month later. July 28, 2016
