Flexible piping for intake

Flexible piping for intake
Hey guys, I'm working on trying to optimize AITs/cooling in my car and I'm curious how bad this would be for flow:
I'm running a low mount C30-74 rotrex and the intake piping is EXTREMELY close to the header. Currently to make everything fit I have a metal pipe next to the header. It's never gotten hot enough to burn me, but I'm sure that it's doing a great job of heating the charge pre-compressor. I was thinking the flexible piping would be better at insulating the intake air from the exhaust, and I may be able to route it a little bit further from the exhaust so I can put some decent heat shielding between them.
Here's another angle on the intake pipe. Right now the lower rad hose is being pinched as well. Flexible hose would allow me to make the weird compound curve around everything, but I'm concerned about killing the flow to the compressor... Anyone have any input/data on this?
****. Just had another thought, this stuff might just collapse from the pressure drop at WOT
Any ideas/input is appreciated.

i dont see a problem with your current setup. besides the sharp 90 degree bend, which i would replace with a metal 45 degree piece, it looks fine.
and i dont really see any way to not have the intake next to the hot header.
that rubber/plastic flexible piping will melt. but you can use metal/aliminum flex pipes, like the one's for clothes drying machines. just get the good ones with thick metal, not the aluminum foil kind.
i doubt it will decrease the intake temps though.

You're better off adding a heat shield and maybe wrap the intake pipe in a thermal barrier material. I know it's frowned upon and potentially has long-term issues, but you will likely benefit from wrapping your header as well.

My main concern is that I hit AITs of nearly 100° when it was barely 30° outside. Currently the intake is so close to the header that if I put a shield on it one of the two will likely be making contact. right now my finger doesn't even fit between the two.
I guess for now I'll double down on my ducting to the IC. I just want to consider all of the places I can make an improvement before I start making changes.

From what I have seen, it should be better, but I don't want to put a RB on a 1.6 (waste of $$). I'll buy one when I go 1.8
The inlet is not 100% sealed, but is pretty decent right now (LRB undertray). Linclonlogs is running the same intercooler setup and his intake temps are way more reasonable than mine. His charge piping is further from the exhaust (different SC mounting location) and he likely has better ducting. I'm gonna do a bunch of finishing duct work and see how that plays out. IATs drop fast out of boost, but I'd like them to stay down...
