2.4l Intake Manifold
#4
you can swap the intake manifold with an adapter plate for your throttle body, the intake manifold used for this is the one piece 2.4 mani. best to buy the kit from crate engine depot. using the 2.4 throttle body requires a tune not to mention rewiring your tb connection, plus since you are an 09 the 2.2 tb has a 6 pin connector and the 2.4 has an 8 pin connector, not impossible but you need that connector,here is the kit for the intake. now the dyno they did was on a modded cobalt so expect your gains to be a little less.

I have the Crate Engine manifold on my 2.2, 2008 LT.
Love it!
My highway mileage jumped from 31 to 35 MPG, and that is in the DC/Baltimore traffic area. In town went from 25 to 28 MPG.
I also added a CGS cold air intake.
Tech help with Crate was great, I had a few "lack of attention" mistakes.

Bringing this old thread alive again, but if you have a 2008 2.2 will the 2008 2.4 be a straight swap or is there still an issue with fitting and pins etc
