I was reading on the challenger talk forum about people installing the 6.4L intake and wiring up the variable intake runner controls. Looks like they are gaining 20-25 rear wheel lb/ft in torque throughout the lower rpm ranges from the long intake runners. With a used intake and the necessary sensor/wiring cost should be under $600. Seems like a very cost effective mod for gains where our trucks would benefit from the most. Anybody with experience on a ram with this mod?
