GM Stage 1 Sensors
I’ve been looking high and low for these sensors. They were the exact same types used in my 09 Chevy HHR SS I just acquired. Totally glad I purchased them and with its overall performance. Thank you to ZZperformance for having them available

Easy and fast to install
Had one pin push in on the wiring connector - pushed it back into place, reconnected and I was good to go. Took about 10 minutes to install.

Needed sensors
At 25 psi, the stock sensors were throwing codes. Replacing them with these stage 1 sensors didn’t help at first. The ECU was tuned for stock sensors. Once the ECU was reprogrammed, for these sensors, the car started running great with no CEL

Tune
They were great with my tune I am very happy and satisfied car runs like a v8

GM S1 Working, Not too Difficult to Install
This was a fairly straightforward install on my '09 SS Turbo with some slight changes. The harnesses are too long but they make the right connections. A long screwdriver is needed for the bottom end and some modification to the part to make it fit well there. There is only one spot for screw on the topside vs. 2 in the stock modult as these don't match perfectly either but it will wiggle in and do the job. Here's a link to a video I used to help with the install: https://www.youtube.com/watch?v=qQXsnVvEZPw&t=7s&ab_channel=JosephDiFeo
