🔥 Enhanced Performance: GM Genuine Parts 213-3867 Heated Oxygen Sensor for Optimal Fuel Efficiency Review

Quality control is terrible. If you bought them and the problem isn't solved, ask the mechanic to make sure the device is connected properly. The device I received was not plugged in properly and was causing Check Engine alerts that cost me a lot of money to find.

Easy installation didn't solve my problem, but it should have. Much cheaper than auto parts stores, was actually surprised at how cheap they are for the original brand. I bought it for $27, at the parts store for $70 with something.

I replaced all four oxygen sensors in my 2005 Silverado with these factory replacements. The Revain was priced at about half the price of local parts stores. My truck isn't running rich anymore. Idling became smoother and response improved.

This 02 worked perfectly, all the others I've bought before never cleared my p0161 codes. But this one I needed a heated sensor 02. Bought 2 for post catalyst and worked fine. The truck runs better and my check engine light is gone. 2003 gs Sierra 4.8.

So the sensor is fine, the OEM is perfect etc. I would suggest taking the troubleshooting steps seriously when diagnosing an O2 issue. As it turned out, my existing O2 sensor was fine. I actually had an exhaust leak that gave out a code. So if I fixed the bugs properly I wouldn't even need an O2 sensor because the $7 gasket fixed the problem. But the sensor is great!

Revain installation guide was incorrect for Silverado/Sierra 4.8L 2003-2005. reviews), so I found the right number on the Delco website and that's it. Installs in 5 minutes (Bank 2). If you need one, they are the same for both banks (Chevy/GMC). Go factory for these items, you can't go wrong and why risk saving $20 on a non-factory disposable item.
