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 Mishimoto Mishimoto 17-19 GM L5P Duramax Intercooler Kit - Black w/ WBK Pipes, listed to fit the 2017-2019 Chevrolet Silverado 2500HD/3500HD with the 6.6L Duramax V8 (L5P).
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. Battle Born Off Road lists it at $2052.95, and the fitment above is what the listing itself states, not a guess.
