Bosch 15703 Oxygen Sensor Fitment
I purchased a Delphi FJ10565 CSEFI to MFI fuel injector conversion kit and a set of four Bosch 15703 Oxygen Sensors at Amazon for my 1996 S-10 Blazer. They had these products available and at very affordable prices. After replacing the fuel injectors and noticing a marked improvement, I then proceeded to replace the four oxygen sensors. I did not have any problems with the units near the catalytic converters as they were very accessible and they only required some penetrating oil and the special socket to remove and replace. Make sure you warm up your vehicle for a couple of minutes to facilitate the removal of the old O2 sensors. The units near the exhaust manifold are much more cramped to access, requiring 'crow-foot' removers to replace. The right bank sensor was difficult to remove but the left bank required me to take it to a muffler shop as it had nearly welded itself onto the exhaust tube. Thirty-five dollars later and a new tap/retread job, I had all new four O2 sensors on. The level of smoothness is highly noticeable. I thought that the fuel injector replacement had made a sizable difference, but when I added the replacement of the O2 sensors, the difference was remarkable. Without ignoring that my vehicle has now 178K miles, the level of smoothness and performance is outstanding. I will be checking the MPG as I was getting an average of 13 MPG; regardless, the Blazer is, once again, reliable to drive.

Bought 4 of these through Amazon for my chevy blazer. A word of caution: if your blazer has single exhaust you only need 3 oxy sensors, not 4 like all the auto parts store say. 2 before the cat, 1 after the cat.
BalasHapusThese have been in my blazer for about 2 weeks and I have already noticed a boost in fuel economy. I always use Bosch products over OEM, IMO Bosh products are best.
The sensors are a perfect oem fit, and made a good improvement in gas mileage and response. This review is longer than necessary!

BalasHapusI bought 2 of these sensors for my 1998 Chevy K1500 at a local parts store for $80 a piece. I looked at Amazon and they were half the price. I was completely comfortable ordering them online because Amazon makes sure they are compatible with your vehicle and I knew Bosch was an OEM supplier so they would last a long time. They were easy to install and plugged right into my factory wiring harness. Whenever I have to buy oxygen sensors again, I'm definitely checking with Amazon.

BalasHapusI changed all 3 of the sensors on my 1998 Chevrolet Blazer. Fortunately the old ones came out easily. These new ones fit perfectly. I had the Blazer smog tested after the installation. The tech was shocked by my results. He said my readings were as low as a brand new car. I'm very happy with my purchase.
BalasHapusNothing else to say really. Amazon had the best price for the exact same part. I was able to buy both for the same price as one locally.
BalasHapusI highly recommend half the price of auto parts stores same product ,exact fit works great not no cheap copy
BalasHapusNeeded this for a TBI conversion with a bad sensor - Amazon's price was better than everywhere else. Product fit perfect, had a good connection, and quickly solved my problem. Very happy with the quality.
BalasHapusFelt like i got some kind of a two for one deal. Got a good product worth every dime on time!
BalasHapusEven though I did not pay attention that I had ordered the wrong item when I got it, it was in perfect condition, very affordable, and received in just a short time.
