Was reading up on that, but most people say if that's a problem I'd get a check engine light, which I don't have on.
If you were trying to squeeze every drop of performance out of the engine when running it at WOT, the engine’s tune would need to be modified to take into account the air flow characteristics of the non-stock intake system. In other words, the computer doesn’t really care about the non-stock air intake because it can compensate for the difference in airflow on its own (by monitoring the oxygen sensors and adjusting gas accordingly) when operating at less than full throttle (WOT).

And to make sure I'm following right, I pull off the intake and run the vehicle in idle to still see if it bogs without it on ? I am a bit confused about going into the intake Plenum however.
still a newbie here so I can't put a picture here ye tbut my intake it's literally just a straight pipe with a filter, nothing else. can go to the AEM site put my car model ( 2007 charger 3.5) there and go into the PDF installation and you'll see how it sits if you wanna see what I mean
You should never try to run the engine without something in place to filter the air it is breathing in. Also, on a computer controlled vehicle such as yours, starting it and letting it idle with no air intake on it would likely result in all manner of codes being thrown and the Check Engine light illuminating on the dash.
What I was detailing in my last post was removing the AFE stuff with the engine off and just inspecting the AFE device after taking it off and disassembling it.
So while I’m thinking about it, I meant to ask before if you are running the air conditioner or defroster when this behavior is heard. If you have either of those on while listening to it idling up and down, turn them off and see if that stops the erratic behavior.
The engine will idle up a little when the air conditioner compressor kicks on, and it will idle back down when the compressor kicks off. So if the compressor is cycling on and off more than it usually would, you could perceive that as a problem with it idling when it’s actually behaving the way it is supposed to (but the reason for the fast cycling of the compressor would still need to found eventually).

I do have the Car manual aswell and in the back of the book it even shows at around what milage should be changed on the vehicle and such, and by the looks of it, it was all well kept.
I would still suggest checking out the CarFax page mention earlier. They have a pretty useful app available that makes it a breeze to keep track of all the stuff you do to the car or have done by someone else, and you would need to create an account on that page to use the app.

They could certainly investigate for you, but the cause of your issue is likely within the wheelhouse of just about any mechanic shop that has good mechanics. You won’t need any specialized services to find and fix it IMO.
Here is a post of mine from another forum where I list out some of the regular maintenance services you might want to do (or have done) to your car. While you are not at the 100K mile limit that marks the end of the parts’ service lives, you are well past the 5 year limit that goes along with that 100K number. So if those things listed in that post have not been done to your car yet, you should look into having them done pretty soon, or you risk premature breakage from failure due to age.
