Thanks to Speedlogix & Mikey & Yo-El For the info about the hellcat lower intake box I decided to take a chance and do it myself and for the 3.6l challengers
My car is currently in the shop but I will get it back Saturday and I will go ahead with the step by step procedures on how to make this lower intake box work for us 3.6l out there

Okay I got started on it as soon as I got my car back from the shop I took off the original lower intake and installed the hellcat lower intake
The hellcat box is bigger than the original 3.6l lower intake box

I had to go back and revise a plan on how to use the hellcat lower intake headlight hole so I went to a local auto store and picked up a 3inch spectre intake tube and it fits perfectly inside the hellcat hole

Here's an example

Took the hellcat lower intake back to my car and with the tube fitting be on there I couldn't get it in to fit so I had to assemble it piece by piece when I brought it back to my car and removed the drivers side plastic panel piece and stuffed the inlet tube through a tight opening but it's enough to fit it through with no problem

I can't wait! I just ordered my hellcat box and inlet tube from Steve White Motors this morning along with the 392 chin spoiler. Got a great deal on both with shipping. Thanks for thethread on the hellcat box mod, it will definately help.

Subbed

Subbed for future reference.


I'll be doing this to my Wifes '15 SXT in a couple of months.


Anybody notice any performance enhancements with theirs since doing this?


Better yet - anybody have any exhaust recommendations to go with this?

I have a 2011 Dodge Challenger with functional scoops that's why I used a tube pointed up so the air the comes in will travel down to the tube.15's and up have the hole in headlight I don't.yes I have notice a big difference with this mod I also have 2 dual 40s flow master exhaust,resonator delete,custom tuned.
