Ever seen an intake like this?

I picked up a 2006 Charger Daytona R/T that has an aftermarket intake and hood. They appear to be a matched set because the intake is fitted to the hood, and seems that it pulls the cold air in through the hood into the top of the intake. I did some Google searches and Google lens on the photos with no hits.

I'm trying to figure out is this setup any good? Would it give better performance than stock or your typical CAI?

Also I have no idea if it has a stock tune, or if someone tuned it for this new setup.

Any help/info would be appreciated.

Well that is kinda cool.

Like to see under the engine cover / filter deal for sure!

Looks awesome, except for driving in the rain. Plus it appears to be hitting the hood on the passenger side.

This is what it looks like with the filter off. Under where it says Hemi it connects to the intake, so the air goes asking the top and sides of that box. I had it off but didn't take any more photos.

The filter is dirty and there is no part numbers so I have no idea what to replace it with. It's blue so it's not a K&N, so I'm guessing it's not a good idea to wash and oil it with the K&N kit. The closest I could find is K&N 33-2591 that's about 1/8-1/4" too long but I'm sure I could trim it s little to make it fit.

How does the flow area, minus the solid structure, compare with a stock filter? How does the air get into the throttle body? Air doesn't like to make sharp turns.

Then you would be disappointed with how the 5.7 intake looks inside!

Ahhhhhhhh, no wonder a lot of us have never seen it before!

Inside the 5.7 intake, right after the TB it ducts it straight down into the middle of the intake. Which from a flow standpoint would help distribute air evenly across the front and rear intake passages.

But it is a Sharp angle downwards and no where as "open" as the 6.4 intake

What about on the Ram truck 5.7, with the TB pointing up? Seems it would be a more direct downward flow.

No clue on it. Never looked into one. But I do know they were SRV equipped.

I don't see any reason why you couldn't. Same concept, same material.

Out of curiosity, as I don't know that much about hood scoops, does one realistically get much air flow into them? The reason I ask is I was reading a review on a vehicle with a factory scoop (don't remember the make, but something older out of the late 60s like a GTO) and the author said the hood scoops on that particular car don't get that much airflow realistically - they are more for looks. The air movement over the front of the car causes a majority of the air to flow mostly above the scoop and not into it. Like I said, just curious and figured you folks are more knowledgeable than I.

Functional air scoops work well on older carburetor vehicles, like Chevy's cowl induction or Mopar's air grabber.
Not sure how much they add to today's computer controlled throttle bodies.
A lot of cars have scoops just for looks too.

Computer controlled TB do not change any function of a hood scoop or intake. There is still throttle plate/butterfly. And fresh quick air is still fresh quick air no matter what engine setup

I found a K&N filter that fits. It's from a 1977-1995 Porsche 928. 33-2591 Air Filter; PANEL; H-0.938 in.; L-6.188 in.; W-20.25 in.;

I did some measurements and the throttle body opening has a diameter of about 3.125" for an area of about 7.7 in². The opening under the filter minus the slats is 67.5 in², and the air path is much wider than the throttle body opening, so I assume it should have good air flow, cold air too. I'm not sure what kind of turbulence the air path might cause though. My very crude sketch of air paths in red and throttle opening in blue:

Regarding the scoop and airflow (yea, late reply but anyway):

At idle a 5.7 will flow about 30 liters or one cubic foot of air per second. At 5000 rpm that'll be about 230 liters or 8 cubic feet per second. While that scoop will help get cooler air into the engine, the intake holes are too small to create ram pressure, and as the scoop is not raised, the intake sits in the boundary layer as the car is pushing through the air.

It is functional for sure, unlike many "humps" in the hoods, but not a miraculous power adder.

Edit: well actually, one might be able to get positive pressure beyond speeds of about 40 to 50mph. If I'm not too tired to calculate, that is...

even the "shaker" equipped challengers still have regular airbox and filter. Im sure they help some but its not enough supply to be the only source. looks cool.
