Uber Ghetto Tupperware Airbox / Cold Air Intake
My latest cold air solution... It won't work for everyone, but if you can't weld aluminium and can find a Tupperware to fit in your available space (wherever it is), you may be able to borrow the idea... Looks like *** but so far, it seems to work...
This is with ITBs in a NA with no headlights and a civic rad swap. Could work with turbo cars, NBs, NCs, etc with the right size and shape Tupperware and creative ducting...
It's completely airtight and so far, vibration resistant. I will be zip tying the lid on during events. Collars are riveted in place and sealed with Sikaflex.
1x Tupperware Modular Mates 5.5L container
3x 4" Downpipe Collars (local hardware store - Home Depot should have them)
1x 4" Pod Air Filter
Some PlastiDip paint
Some 4" Flex Duct
4" Velocity Stack

At what point is the hose big enough to not have that effect?
If I had like a 24" diameter corrugated hose would it be the same as having a smooth 2" pipe?

I did say it was ghetto - will get a better idea of intake temps next time out (9 April).
ITBs and RHD - yes and yes. But it is a concept that with the right Tupperware should work elsewhere, heat permitting.
The hose is double walled silicone flex duct. It is smooth inside - not like dryer duct or HVAC duct. It does rough up some on the inside of a radius but otherwise, it's pretty good stuff. Besides, it's 4" which is about 1" more than my car needs to breathe with aspirated ITBs. YMMV.
As for heat, the Tupperware can handle a microwave - it should survive on the cold side of my engine bay - but time will tell. If it fails, I'll try something else.

Polyethylene and polypropylene in the grades for injection molding or blow molding generally don't start to melt until above 300 degF. Your radiator overflow tank, washer fluid tank, and brake fluid reservoir do not melt!

Be careful how you use the downpipe collar. If it protrudes beyond the air filter's internal velocity stack, then you've created a reentrant pipe end, which is the worst possible configuration. Consider:
Fix is easy, trim the collar end down or relocate the air filter so that the internal velocity stack becomes the entry feature.
Likely doesn't affect you given NA + 4" diameter, but if someone reproduces this with smaller diameters, they might be in for a nasty surprise.
