So I want to try and increase the efficiency of my 350SDL and that added power from a intercooler wouldnt hurt either lol. Im just wondering which is better as far as efficiency is concerned? The air to air obviously requires the piping to do it, where as the air to water does not but the air to water setup is gonna be a little more complex. Has anyone added either types of intercoolers to their diesels? How hard was it? All help is appreciated!
