Please note that after the Air Box is removed the headlight plug needs to be removed by simply lifting and lightly pushing the three clips outwards and it will pop out. It can then be discarded or saved for some future use.
Excellent to the point video step by step ! Addition steps needed: Wrap the air box in thermo shielding. Wrap the shaker to air box tube double wrap with thermo tape !
Good job, I modified my box back in 2015 before they offered that tubing. Plus I covered the top above the filter because the rubber doesn’t seal to the hood properly without the fire wall sound insulation.
I actually spaced mine up about 3/4" so that it pushes the seal against the hood insulation. I also made a plate to block off that cutout in the front edge....that notch allows for a lot of hot air intrusion from the cooling fans/engine. Between the inlet tube, block off, and raising the box, the IAT drops like a rock in stop n go driving. It also stays right at ambient during steady state cruise, usually within 1-3*, which falls inside the delta of the sensor.
HemiSphereCars no, mine is a regular Scat Pack. I started tinkering with the design after reading about some of the hot air intrusion people were dealing with.
i did this mod on my scat pack shaker. i noticed that the airbox has no lid, and instead has a rubber piece around the top with the air filter exposed... just like yours. Heat soak is a very big issue. the airbox gives you the impression that it seals to the hood of the car, but does not. air will take the path of least resistance. most of that filter is aimed at the big open hole where a lid should be and ingesting a lot of engine bay heat. I used some cheap weather stripping for a temporary fix. made a HUGE difference with air intake temps. i'm thinking about making a more permanent seal with some flex seal sculpting. what do you think? have you done anything else with your airbox?
Hi Modern Muscle 180, I did not realize it was a poor seal, however I traded-in the Challenger for a Jeep JLU Rubicon over a year ago so can not test. I did not do any other modifications to the air box. Sounds like you had a good idea to seal it better!
2023 Shaker & used the MOPAR part, install went ok, but the add on tube was kind of to big & creating pinch / twist in the MOPAR tube, it still moves air, but not totally impressed with the fit. Any ideas ? Thanks in advance.
Mine fit fine, maybe take off that long cover and push the tube in a bit more into the dummy headlight space. If seated correctly on the tub then perhaps trim the end that goes into the dummy headlight area. All bits of the plug removed? Hope it works out. Thanks for your comment.
@@hemispherecars5616 I bought the car to my dealer, the 2023 has added a part to the light that restricts the boot from fully seating properly, called the (DRLM) Daytime Running Light Module, so as you stated, trimming will have to happen when I find the time & patients to go through the process again.

I just took out the passenger side headlight plug to bring in more cool air to the engine compartment. I believe they do that on the Demon. There is not much space left on the shaker intake box which now has two forced air inlets. That would be a lot of custom piping, I have to take a look.
I have the same car and thought about adding the tube as well; my concern was also the tune; if you add more wit to the engine then wouldn’t the engine sensor think you would be running too lean? I asked my local dealership this question, assuming a scatpack without the tube would have a different tune from the factory then the hellcat; the dealer service rep said not to do it because yes, the ECU is tuned to not receive this extra air and is not a learning ECU so it would not adjust the air/fuel ratio. I don’t really trust service advisors as being engineers but it still concerns me. Makes my wonder why the factory didn’t add it because I do believe it would promote cooler air being added to counter the warm air from the engine bay. Question, what have your air temps been after installing tube?
The Challenger did run a bit cooler, noticeable at traffic signals since I could check the gauges while stopped. As far as faster, the car is so fast there is not any way to tell without doing test times at a track and I did not do that. Thanks for the comment.
Like the shaker intake it drains to an opening. You would need a large stream of water flooding in to have any problems. The Hellcat has that intake at the light from the factory so Dodge engineers figured out what to do about water. I do plug it with a rag when I wash the car, since pressure washing the filter with water would lead to more maintenance.
As I recall the 6.4 Hemi none shaker has a different air box, no rear inlet for shaker tube of course, and shape facing the headlight plug in different. You could view others doing the Mopar Tube installation on a 6.4 and see the difference.
That was my thoughts.. at least the SXT's and RT's are using the scoops for cool air into the engine bay... so they are not just cosmetic.... but shaker has that scoop why not put to use? ROFL.... come on Mopar.
If you get a shaker hood you will also need a shaker intake scoop assembly that sits on top of the engine among other parts if you want it to work. Good luck, it should be a fun project. I am not sure if the 5.7L and the 6.4L parts are the same.
When the car is in motion the Shaker and the cool air from the Mopar tube at the headlight area are producing positive air pressure so hot air will not enter from the hole at the bottom. The actual Hellcat air box also has the opening on the bottom of the box. Putting a plate with small holes may help increase positive air flow at speed but I am not sure how it would affect it at idle. I have actually been pondering installing a lower plate for some time now. Thank You for your interest.
The hole in the bottom of the airbox mates directly to the opening in the fender well. It seals against the fender, drawing air in ONLY from the fender well, OUTSIDE of engine compartment. That is the same for ALL Challengers. Take your airbox lid off, pull your filter, and look down. Yours has the same bottom hole. The only opening that pulls air in from the engine bay is the rectangle opening at the top front of the CAI air box, and any that might leak in around a faulty box-to-hood seal.
Do not plug the bottom hole. It does not pull from the engine bay. It pulls from the fender well, with a foam seal isolating it from the engine bay. You should have seen that when you did this video. Before adding the headlight duct tube, that bottom hole was actually the ONLY source of truly "cold air" your intake was getting. Don't eliminate that. :)
Please note that after the Air Box is removed the headlight plug needs to be removed by simply lifting and lightly pushing the three clips outwards and it will pop out. It can then be discarded or saved for some future use.
Not in 2023 models. The plug is fastened using 2 Torx 10 screws and is much more difficult to remove.
Excellent to the point video step by step ! Addition steps needed:
Wrap the air box in thermo shielding.
Wrap the shaker to air box tube double wrap with thermo tape !
Thanks, good idea to keep the air cooler!
Just put mine in yesterday. Your video was very helpful, no guess work
Thanks, I tried to make the video so that it would leave out any guesswork and be efficient.
Good job, I modified my box back in 2015 before they offered that tubing. Plus I covered the top above the filter because the rubber doesn’t seal to the hood properly without the fire wall sound insulation.
Crazy55 Rider Thanks I'll take a look at the upper seal.

Do you have a Shaker?
HemiSphereCars no, mine is a regular Scat Pack. I started tinkering with the design after reading about some of the hot air intrusion people were dealing with.
Check out the only two videos I put up after heat shielding everything. I got my intake temp to just under 5 degrees while running.
Thank you sir for that video. Now I want a shaker even more
Hi Ayo Taurus, did you ever get a Shaker?
Nice, clean install. Even though it has it's hiccups, it's still a great video
Thanks for you support!
@@hemispherecars5616 i ended up putting that on my car as well

@black6turbo i didn't know there was a lid available for that airbox.
Nice work man
Thank You, I had to edit it about 5 times to get it to this point.

Love this video super informative. Do you happen to have the part numbers for this mod?
I do not know the part number. It's is just the Hellcat cold air intake tube about $60.00 You can get it on ebay from Steve White motors like I did.

Would there be a way to add the second headlight intake to this system or would that be to much piping with out turbo
I just took out the passenger side headlight plug to bring in more cool air to the engine compartment. I believe they do that on the Demon. There is not much space left on the shaker intake box which now has two forced air inlets. That would be a lot of custom piping, I have to take a look.
I’ve seen so many ppl do this and I been wanting to do this but the only thing holding me back is that I don’t know if we need a tune after?
Shouldn't need a tune
A tune is not needed, never did it to mine and it always ran great.
I have the same car and thought about adding the tube as well; my concern was also the tune; if you add more wit to the engine then wouldn’t the engine sensor think you would be running too lean? I asked my local dealership this question, assuming a scatpack without the tube would have a different tune from the factory then the hellcat; the dealer service rep said not to do it because yes, the ECU is tuned to not receive this extra air and is not a learning ECU so it would not adjust the air/fuel ratio. I don’t really trust service advisors as being engineers but it still concerns me. Makes my wonder why the factory didn’t add it because I do believe it would promote cooler air being added to counter the warm air from the engine bay.
Question, what have your air temps been after installing tube?
The bottom of the air box is open. Mostly you are just getting cooler air not much more. It does run cooler especially when stopped.
No the map sensor adjusts to any small change this would make, although I would also argue that a tune is needed on a new stock hemi ;
Did you notice anything different with it? Any faster?
The Challenger did run a bit cooler, noticeable at traffic signals since I could check the gauges while stopped. As far as faster, the car is so fast there is not any way to tell without doing test times at a track and I did not do that. Thanks for the comment.
So do I just need to buy the tube? I was about to buy the lower airbox w/ the tube, but if I don't need to spend money on the lower airbox I won't.
If you have a 392 Hemi Shaker all you need is the tube.
HemiSphereCars i have the 5.7 shaker. Does that change anything?
Where did you get the lower box ? Thanks
That is the factory box that comes with the 2017 Challenger Scat Pack Shaker. Thanks for your question.
What is the shaker doing? I thought the idea of the shaker was to ram air into the intake?
It's just adding to what the shaker does.
This may be a crazy question but what happens on a rainy day.
Like the shaker intake it drains to an opening. You would need a large stream of water flooding in to have any problems. The Hellcat has that intake at the light from the factory so Dodge engineers figured out what to do about water. I do plug it with a rag when I wash the car, since pressure washing the filter with water would lead to more maintenance.
Is that the factory intake, or the aftermarket MOPAR CAI?
It's the factory Shaker box with the Mopar Hellcat intake tube installed at the headlight plug area.
Cool. Does the non shaker have the same intake?
As I recall the 6.4 Hemi none shaker has a different air box, no rear inlet for shaker tube of course, and shape facing the headlight plug in different. You could view others doing the Mopar Tube installation on a 6.4 and see the difference.
On a non-Shaker you need the Hellcat lower box as well as the Hellcat tube shown here. @@jmdhintz
i would think the shaker provides the most air !!!!! i would
hook shaker directly up to intake ,,,,,,,,,,,,,
The shaker does go directly to the air box, water is redirected and the Headlight MOD adds more air volume to that.
That was my thoughts.. at least the SXT's and RT's are using the scoops for cool air into the engine bay... so they are not just cosmetic.... but shaker has that scoop why not put to use? ROFL.... come on Mopar.
The scoop is hooked up to the air box from the rear Bud, this just adds some more. @@jonathanxmrmudrider2386
Nice mod , what are the hp gains ?
Mike Point they say 5 to 8 horsepower gain at speed only. I never had this on a dyno.
They say 5-8 horsepower at speed. I did not Dyno tune so not really sure. does run cooler, but I do not have before and afters statistics.
@@hemispherecars5616 AT 5,500 RPM'S?
A dyno run would not help anyway as there is no ram air effect while not moving. :
I want a shaker hood for my RT.
If you get a shaker hood you will also need a shaker intake scoop assembly that sits on top of the engine among other parts if you want it to work. Good luck, it should be a fun project. I am not sure if the 5.7L and the 6.4L parts are the same.
Super expensive for the many parts needed.
Were can i buy it
mlunden11 you can buy it at Steve White Motors in North Carolina online
Steve White Motors in North Carolina. They advertise on Ebay that's where I ordered mine.
Waste of time and money, what about that hole in the bottom of the airbox?
still a load of under hood heat there.
When the car is in motion the Shaker and the cool air from the Mopar tube at the headlight area are producing positive air pressure so hot air will not enter from the hole at the bottom. The actual Hellcat air box also has the opening on the bottom of the box.
