Does anyone make an under the bumper fresh air duct that connects to a 4 inch hose?
I have an LS swapped 70 Charger that Ive learned would really benefit from cool air after driving it this week with the hood removed.
I'm trying to avoid cutting into my clean core support or inner fenders, but I will if there's no other option.
Surely someone makes an under bumper/core support fresh air inlet right? So far, Ive found a 69 Olds 442 air scoop (for 350 bucks!) and a Dodge Viper brake duct inlet that is oddly shaped for what I need.
Surely someone makes something right? You guys have any ideas on where I could find one?
Under the core support/valence.

Woodworking dust collection uses 4" hose and has a variety of scoops and chutes available.
In reply to ShawnG :
That is an excellent idea. I'm not a woodworker and have never seen these.
Amazon has this one I could attach to a front chin spoiler and hook up to an inline air filter.

Big box store has all kinds of prefab things like that in the HVAC aisle.

Post a picture of the hella cool cold air scoop from Monzora.
What about picking up dirt and dust and rocks and water from low down?
This could be a great use of a NACA style duct on the front of the hood. Wide and shallow, change to a panel style filter, and get rid of that 90* bend at the same time. Or if you need the intake length, split it and do 2 NACA ducts on either side of the hood to keep it looking symmetrical.
Isn't there a version of the Charger with a nice big hood scoop from the factory?

I'm guessing there is no way to run a vette style low but wide intake scoop going over the radiator support?
I am sure you know this but be carful not to suck in water with a low mounted air intake. (Ask me how I know this 😳).
