To take it another step (?), beyond the possible cooler EGT's ?
Turbo's can, and will, compress cooler (more condensed) outside ambient air, more efficiently.. than Warmer air, drawn from under the hood... which is also, somewhat restricted by the clearance between the radiator support cowl, and the air filter inlet snorkel.
Theze Dezel's need Massive amounts of air. The "Zoodad" allowz for that. Cooler air too
