I have a ‘19 and did this a few months ago. Removing the caps from the back of the headlights is a pain. Tiny little set screws on both sides of each that take a T9 or so...and little hands to get to.
For the Hellcat box I used a pre 2019 and just trimmed the front of the intake tube a little (around an inch) so it fit but if I were to do it over again I’d save an hour and just get the shorter tube for sure.
In my opinion this is the best intake for these cars, and without a doubt best bang for the buck! Sure it only picks up around 5hp and likely only that much at speed but under $100 and took me about 2 hours (cap removal and cut to fit being most of that). I’d make that trade a dozen more times.
