Great product have been a GM tech for 18 years these things are perfect. Couldn’t believe it so had to order . Good quality and performance is spot on!! Thank you !!

UPDATE -after 2 months of use - my SEL was glowing again & i ran my codes & had 6 ECM codes all due to these oxygen sensors.i replaced with the correct part numbers as the ones i pulled from my trucki have a shop scanner capable of bi directional commands, active tests, freeze frames, etc..all 4 sensors were throwing codes for resistance, voltage, etc.the post cats were over voltagethe wide band AF sensors were not performing at all - caused my engine to run lean & thus, parked for a week so that i could undo the damage that i did by cheaping out on these sensors.worst of all were the cat efficiency codes.... i have an older, high mileage GM .... still running factory cats... they are delicate... these sensors resulted in bank 2 cat running low efficiency... not goodcost me more in the long run than what id of spent jsut going ac delco... or GM gen...my advice to anyone considering these & trying to save a few bucks... DONT ... you willl regret it in the end... & for the majority that do not have the automotive mechanical ability & skill that i do & the tools & machinery to quickly & more efficiently pin point the issues like mine can... this will wind up costing you even more... so please take my advice & invest in your vehicle.... you put your life at its will - along with those of your loved ones each time that you get behind its wheel.... just my 2 cents....

My mechanic told me these were faulty, so we installed and it worked. Compatible with my 2006 Chevy Silverado. Much cheaper than the auto parts stores in my area.

They work, arrived on time. But they were opposite of the ones I was replacing. The female end I took out was the male end and went to the further back sensor location than the front it replaced. But they worked and it was a hell of a deal. For the price of four I couldn't buy one elsewhere. I'm happy with them.

This was perfect. Great price. Great packaging. Came fast

The plugs are definitely different it was supposed to fit a 2006 4.3 Chevy Silverado

just what I needed to fix my truck. easy to install

Replaced for different codes that appeared once a week. Put these in and P0054 and P0060 showed up as soon as I started the vehicle. Cleared them TWICE and of course they returned. Too late to return them... :-(
