Hi guys I am a owner of a 09 Cobalt ss/tc. I have a K&N SRI and a zzp downpipe. Just got the car like 6 months ago so I am looking in to doing a tune. I am looking in to ordering the 3 Bar sensors. I have found two links for them but I really don't know if there is a difference. Any advice would help.

Here is the Stage 1 sensors

Cobalt, Solstice, HHR Stage Kit 19212670HK

Here is the Other link from zzp

GM ACDelco - GM Stage 1 Sensors #

GM ACDelco - GM Stage 1 Sensors #

just want to know if there is a difference. I already saw the guide to the different LNF tunes but it never answered my question on the senors

The link from zzp is what you need. But your tune will need to be updated for the new sensors immediately after install.

 

for all purposes will the zzp work if i wanted to do a GM Tune?

 

Yea, those sensors with plug n play harnesses and o rings are apart of the gmstage 1 kit that you need before the tune.

 

The plug and play sensors are cheapest from performanceautowerks. If you want a gm tune you need the stage 1 kit and have to go thru dealer for tune and install.

 

My cobalt ss/tc is paided off so warranty is not an issue. What would you recommend gm tune or a tune from zzp?

 

An HP tune.

 

Get a hp tuners tune.
