hey guys,
I was wondering to see if any of you ended up changing your 02 sensor the upper one which is located right next to the turbo. I have been getting check engine lights and its Po172, so if you have changed yours before please let me know what brand and how did you install it thanks. I went to Kragen they have the OEM one which coasts about $300+ and universal one for $58, but the universal one needs to have some wiring work done. thanks.
