Review on MOSTPLUS Oxygen Sensor O2 4pcs Upstream + Downstream Sensors Compatible with Cadillac Escalade Chevrolet Avalanche Silverado Tahoe GMC Yukon Sierra 213-4229 12609457 by Marco Wilson

I had two damaged OEM sensors on the intake. They appear to be a quality replacement with a precise fit. Remember that O2 sensors usually get damaged for some reason. I found that the wire was rubbing against the front driveshaft which could have caused a short. The fuse is also blown. A few issues so I just replaced all four as a reset as this set costs a lot less than a single OEM replacement. Installation is easy, but not easy. Very narrow and difficult to get to. But these replacement parts fit the same as OEM.
