      Be advised that website also shows a NGK sensor that has a different connector but still shows it as an exact fit for an 05 trailblazer. Make sure you order the correct connector for your application.

        wanted to use the Delco/GM sensor, but not in stock at the local store. I used the NTK and it performs perfectly!

          Comments about NTK Oxygen Sensor:

          Used to replace an original o2 that hadn't set a code but appeared to be switching slowly when scanning in HPTuners. My truck immediately had better response and picked up just under 1mpg. Plug and play install- used an o2 socket to remove, plugged in and torqued down the new sensor, and life was good. Took less than 2 minutes on a COLD engine. Also it was coated with anti seize which is a nice plus.

                A:

                Most of the NTK Oxygen Sensor comes already coated with anti size, this part NTK Oxygen Sensor, Part No. 21054 manufactured by NTK should be coming coated with anti size, but if not, apply (enclosed) anti-seize to oxygen sensor threads.
                For compatibility of this part with your vehicle, please provide your vehicle make, model and engine specification.
