🔧 High-Quality MOSTPLUS O2 Oxygen Sensor Set for GMC Sierra 1500 5.3L (03-05) - 15284 SG1857, Pack of 4 Review

Great price but problem is getting them in my truck. The car dealer wanted $250 for each install, I installed all 4 of mine in an hour and borrowed tools from the auto parts store for free when I returned them.

After checking with my local parts store they wanted about $60 for one, here I got all four and they worked great. Replaced for a friend and after I installed them he said he couldn't remember his truck running so well for years.

My Check Engine Light came on in my 04 Silverado. Code scanner said O2 sensor. I have relied on these inexpensive sensors and they have not let me down. I swapped all four at once and my check engine light stopped coming on. It's been a few months since I installed it.

Everything looked very good. Turn off the engine light due to sensor 02 heater circuit malfunction. All four original sensors replaced at 330,000km. I was hoping for an improvement in mileage, but apart from turning off the lights, everything stayed the same. 2003 5.3L Silverado 4x4, retractable cab, step, 4.10 gears.

I received the engine verification code for my 2004 Chevy Tahoe 5.3L V8 Z71. It turned out that two of the four O2 sensors were not working properly. I decided to replace all 4. They fit perfectly on my Tahoe with no mods. The engine codes are fixed and my Tahoe runs like new. Great price, especially when compared to local dealerships.

Although this sensor solved my problem the plastic bolt to reinstall it on the car is too flimsy. When I tried to insert the plastic plug into the base, the barley touched the rim of the hole and the pin broke off. I was able to attach a zip tie to hold the sensor and get the job done, but it added another 15 minutes to the task. Again, as long as the sensor works.
