While I don't have any working knowledge of either of these products, I can say that there is a lot more to the products than just what they look like in pictures. Material quality is a big one that I can see greatly changing the performance and cost. A low cost material can break down quickly based on heat. Depending on the mixture in the polymer, heat causes plasticizer to be released from the structure. The plasticizer is what keeps polymers pliable. Once they become brittle after a number of hot/cold cycles, the material begins to break down. Your turbo could easily start ingesting broken pieces of intake. Add in crankcase vapor and the process could easily be accelerated. The material thickness can also aid in insulation from under hood radiant heat. A lower grade material will conduct more heat to the induction air stream. There is also developmental, marketing, labor, quality checks, and a lot of other costs that need to be accounted for when releasing a product. Company A could spend a year in development to build the best engineered product. Company B simply 3D scans the competitor's part and finds the lowest cost producer. They don't have any developmental costs to cover or marketing. They just use low price as bait. I have run into this for years in the commercial vehicle market. I have even tested knock-offs of the products I had engineered to see what the competition got right and wrong. It was mostly wrong and really wrong. Products looked the same and even had the same colored box, but they did not perform the same. There is a lot more to a product that what you see in a picture.
I have seen a cheap induction tube go flat, but can't remember what car I saw that on. I am pretty sure it was a Fox Mustang with a cheap intake system and was at the local dealership with engine problems. The tech would rev the engine and the tube went flat. That was the first time I had ever seen that happen. My brother had an '88 Escort GT with a factory rubber tube between the throttle body and air filter. While that one did not get sucked flat, it surely collapsed on itself under throttle.
