what is the power improvents of doing the Intake manifold swap??

 

im not sure numbers wise but its definately somethin appreciable. And you wont be swapping manifolds since you'll be using whats on the a6. And it is necessary to do the dpfi to mpfi wiring in order to run the a6 mpfi engine in a dpfi chassis.

 

ok cool thanks for alll the help
