O2 Sensors worked perfect!
924277
I had a check engine light with a P0133 code. I ordered the Bosch O2 sensors with correct Ford plug ends because they were a few $$ cheaper. When I installed the Bosch sensors my Explorer ran rough and threw additional codes. I returned them and ordered these Motorcraft sensors. I installed them, the engine ran smooth and no check engine lights.
Lesson learned? Only use Motorcraft emission sensors in your Ford products.

I replaced this oxygen sensor on my 2005 Sienna.  The installation was easy and this unit fit perfectly.

My Subaru 2002 Outback went from high altitude to sea level and the engine started stalling in traffic, began running rough with intermittent  racing.  It had done this years ago.  Back then I paid hundreds of dollars just to have the O2 sensors replaced.  This time I figured I could replace the sensors myself. I looked at several web site vendors and then turned to Amazon.  I was surprised that I found the part for my 2002 Subaru Outback.  Amazon even verified that the part was correct for my make and model ("This fits your: 2002 Subaru Outback, 2.5L H4....).  I went to Y__T____ and found a video that showed exactly how to replace the part.  I also went to the free manuals on Autoz***.*om to determine the exact location on my model car.  I did not need to remove the exhaust pipes from the exhaust manifolds so I bought the Powerbuilt 648691 Oxygen Sensor Offset Puller.  I had to put a pipe extension on the rachet, and carefully applied pressure to get the sensor removed, but it worked like a charm.  I bought both the front and rear sensors, and replaced both at the same time.  The plugins were an exact match.  The whole job took about 2 hours, not bad for a novice.

Installation was a PIA when trying to unhook the cable for the O2 Sensor from my bike, but it works amazingly!

Bought this to replace upstream and downstream O2 sensors on my 2008 Ford f-150. Worked perfectly.

The oxygen sensor was perfect for the 2004 Honda CRV.  Same maker as the original.  Easy installation, as mentioned in detail by others.
Cheaper than any local autoparts stores and prime shipping was very quick.

After several "run-arounds" with aftermarket O2 sensors (even Bosch!) and about a month of an intermittent Check Engine light, I finally purchased this AC Delco sensor and cured my problem! I simply used the part # stamped on the old sensor, matched it up here and got an Original GM Replacement part. It's been well over 6 months, and NO Check Engine light! Plus, it was cheaper than the aftermarket sensors! Always use OEM sensors!

These are fantastic OEM replacement O2 sensors, I always seek out the Denso brand when O2 sensors are needed. Just finished installing four Denso sensors and all four worked great and have been trouble-free for a while. They're all switching perfectly and my fuel trims are pretty spot on. My 3800 FBody requires one sensor in each manifold as well as one fore and aft the cat. so being able to save money and still get OEM quality is fantastic. Heck, in many applications Denso is who is making the AC Delco sensors too.

Denso and NTK are the only brands of O2 sensors I will use. I have tried the ones available at the auto parts stores and have received defective units that I had to replace immediately. With Denso this has never happened to me. Spend the couple extra dollars and wait the couple extra days to get quality and do the job once.

Worked perfect for my mini cooper. Husband and I clipped off the old sensor and just soldered the new one on. Have not had any issues. Great cheap fix if you can do it yourself.

Sensor head was a lil smaller than the stock one I pulled out. I put it in today and cleared the o2 code and had the wife drive around and had no check engine light come back on! Sweet problem solved for half the price my local napa store wanted

Very quick shipping/good packaging.  This sensor worked great right out of the box.  Insert batteries... place sensor outdoors... works like a charm!

I am very pleased with the denso sensors. I changed the upper and lower sensors, cleared the check engine lights, ran the car on the street and highway, took it to get it smogged and it passed. :)  oh, and saved a lot of money.

My first time replacing O2 sensors proved to be pretty easy with the help of the instructions included with the Bosch 15730.  Product was of good quality and took only 30 minutes to replace the two on my Cherokee.

Great replacement sensors for my 2003 Sequoia.  I'm always a bit leery about ordering electronic parts for my vehicles and finding out they are not actually compatible.  All research told me these would work well for my upstream O2 replacements.  Bosch has been in the automobile parts business for an extremely long time, and I trust them.  One note for the home mechanics, make sure when you pull the old sensors off that the old gasket comes completely off.  If any little pieces are left on the exhaust you will get a reoccurring code fault.  You might be wise to inspect the exhaust mount area for any debris and clean any rust away with a small wire brush.  Any debris may allow external oxygen into the exhaust at the sensor and you will get a exhaust related fault.
