Did you test it?
Diesels tend to lose power and fuel economy with warm air intakes.
Diesels seem to like their air intake temperatures at the manifold between 30F to 120F.
Below 30F and it seems to delay fuel ignition and above 120 and you cant pack enough air into the cylinders.
Every +1 degree C or F increase in intake temperatuers increases EGTs by that amount, so you are running 75 degree higher EGTs than nessary for no reason.
