Hey Guys new here, but I came across this site & the pic of the 2500Ram-Air style hood.... Unfortunately I was in a.head on collision with my 2015 Denali, but some silver lining here, the body shop agreed to put the Ram-Air hood on it, and since my Bumper, lights, hood, fenders & smaller parts had to be changed out, they did me a solid & did a 2019 conversion..... I have pics before & hooefull get my truck back tomorrow, so will def post those.... 14GMC14 is correct, you really only need to change the hood, duck work added & new 2500 springs, as this hood is steel not aluminium, I don't have a K&N set up, but was thinking of just getting the other top to the air intake, thinking it will actually keep the air cooler since it's kinda sealed. With an open airbox your letting the hot air in from the motor..... But nevertheless thank u for doing it to yours, made me say yes after the accident.....
