2018 Ram w/Hood Scoop
Looks like drittal was right. Ram appears to be adding a hood scoop to increase power output for 2018. The grill shape looks like it may resemble that of the 1500. Link

Yes the new scoop on the Chevy has an air intake. I have an 08, and the killer in diesels is exhaust gas temperatures. I finally did my exhaust and EGR deletes and it runs a couple hundred degrees cooler on EGTs from that alone. Where before my fan clutch would come on a couple times on a mountain pass, now doesn't because the truck is cooler. I've read that an air intake on my 08 can decrease the EGTs another 50-100 degrees. Now I only tow about 8,000 pounds so I could go the speed limit before on passes, but if you are towing heavier, that 50-100 degrees can be 5 miles per hour faster on a mountain pass.
That's mostly what the companies have done is add cooling to the engines over the years. Since they starting using variable vein turbos in the 2000s, stock diesels could get to the same HP and torque and the latest diesels with only a programmer. You just have to watch temperatures to ensure they don't overheat.
BINGO! All three of the modern HD diesels can easily get to at least 500hp and 1000 lb-ft or more at the crank. It is doing it while meeting emissions and keeping the EGTs low is the issue.
It is funny that most people say that intakes are worthelss and the trucks have plenty of air up to 500 hp. Yet all of the manufacturers are starting to add air induction systems for more air. These people neglect to realize that for every 1 degree you cool the air coming in, you cool the EGTs by 1.5-2 degrees so adding an intake does have its benefits.
