An intercooler cools the air after the turbo squeezes it. Cooler air is denser, which is what the engine actually wants. This one is the On3 Performance (2013 - 2018) Ram Cummins 4th Gen Intercooler Upgrade, listed to fit the 2013-2018 Ram 2500/3500 with the 6.7L Cummins I6.

why this one — The gain shows up on repeat hard pulls and towing, where the stock cooler heat-soaks, more than on a single run. On3 Performance lists it at $679.99, and the fitment above is what the listing itself states, not a guess.
