Hey guys. I was wondering what the benefits of putting the 6.1 intake on a 5.7 Hemi. is there a noticeable power gain from doing this or is it more of a mod for looks. Also curious as to what all is needed to swap the intake onto a 5.7. i often see them for sale with the injectors, fuel rail, and throttle body. is all of the needed for the swap or is it a direct bolt on? thanks for the help.
