Worked great on my 2006 Trailblazer EXT 4.2L.
A bear to get the old one out, just cut the wire and use a full regular deep socket. Borrowed tools from the local auto parts store helped get the new one in. The socket they have is slotted to fit the wires in. Use this one for tightening only. Do not try removing the old with this slotted socket, it will strip and turn and break off then you need a pipe wrench.

Absolutely fantastic part!!! Fit perfectly on my 2006 Isuzu Ascender 4.2L.. I bought this one to replace one that I bought brand new that only worked for a week.. even comes with a tube of anti-sieze compound, great little touch to add to an already great product

CEL kept coming on in my 2005 Colorado 3.5L 5 cylinder. Tried cleaning TB and MAF to no avail. Bought this as its half the price as other O2 sensors. Came with little tube of anitseize which is nice. Bolted right up. Time will tell if the CEL comes back. Pictured is the old and the new.

A Great Price on this Product, I had an Engine light on my 2006 Trailblazer come on, This was this issues, The Front Oxygen Senor,Product can with the coating which you plan on the threads. Took about 10 minutes to change , using the Correct Wrench. Photo’s are the New, and the Bad Sensor.

Oxygen sensor failed a few days after my inspection (engine light came on and scanner code told me it was probably that). I bought this one, switched them out in a few minutes, reset the light, and no issues since!

I was getting 12.5 MPG in my Saab 97X, same as a Chevy Trailblazer. I replaced my old one in less than 15 minutes with an O’Reilly’s Auto Parts loaner wrench and now I’m getting 17.5 MPG. As a bonus it accelerates faster and doesn’t bog down when under a load. The best improvement I’ve made to the car. One free tank of gas for every four fill-ups…outstanding
