Get the right one the cobalt has a baro and map sensor. Call 1st and make sure they have the correct one.

i believe the baro is what you want cause it is two bar. the map on those is 2.5 bar. check out hptuners.com/forum.

My Cobalt MAP sensor has never read 2 bar... I've done everything I can think of, and it still won't go over 105kpa...

3 Bar. You will not find a direct replacement AFAIK. You will need an aftermarket sensor reading 0 - 5 volts and run a vac line to it from the intake manifold and then wire it up to the wires that go to your stock sensor.

2 bar - up to 14.5 psi boost.
3 bar - up to 29 psi boost

GM MAP Sensor # 12615136 is a direct replacement 2 bar map sensor as stated by Rick_Vor above.

I don't think you have the right one. Ask KB or get the one listed above and I believe it is the one from the Cobalt that reads 2 bar. Mine reads fine to 13 psi boost but I have not run it out to a full 2 bar yet.
