anyone try flexable intake duct (pre turbo)?

i have a combo of 3" metal and 3" silicone for the intake pipes on my g8. it snakes thru the suspension and is a real mess.
that stuff above looks like a simple way to do it but i have my doubts about it's durability. anyone ever try it? anyone know of something similur but higher quality?
