Really appreciate any input.
If you are looking at the actually intake manifold not the cai then don't worry about changing. There are only a couple options and unless you have a big stroker with a monster cam you will actually lose power.
The truck intakes are all the same upto the 09, the 5.7 and 6.1 car intakes require new mounting brackets to move the AC and alt out of the way.
If you do some web searchs you can probably find a few of the dyno test articals that have been writen about the intake tests.
