Wondering if a Stock Boost Gauge & Stock Pillar from a cobalt 2007 would fit on my 2009 HHR.

If yes, how does the Gauge get connected (to what) vacum hose or wireing setup.

Thanks for your help

 

The pillar piece would not fit. (different rake and lenght).The gauge would not work as it is fed by the ecm and that would have to be addressed by HP tuners or thru a GM dealer. You could use an aeroforce interceptor and plug it into the OBD2 plug. For the pillar piece just get the HHR/SS one and it will go right in.

 

Great info, thank you, I will order the pillar piece for the HHR/SS from dealer, and try find a use aeroforce interceptor gauge, because the new onces are pretty costly.
