I have learned through research here that the 05 Z has wise band oxygen sensor. Finally this summer I will be getting the car tuned. My question are a few. Will an aftermarket wide band be an upgrade and provide better tuning. Second what is a good wide band sensor if I need one, and do I need to get a WB gauge if all I really want is car to run as good as the tune will allow. I would like the interior to stay as stock looking as possible.

Thanks for any help.

 

You can just use the stock ones to get it tuned it on. Usually just want a wide band sensor if you're F/I so you can make sure everything is ok. But you can just get a Bluetooth obd2 adapter and watch your afr's on your phone.

 

You do not need an aftermarket wideband.
