That bolt issue is why Turbohoses spent so much time making the core. Also, that's a big factor in the price difference. Different strokes for different folks. I personally like everything to fit well in my car. That's part of function for me. Form is the aesthetics. That spicy has every right to voice his opinion on the product. He said what he liked and what he didn't. Instead of everyone coming on here attacking him why don't you try coming on and disagreeing with his opinion tactfully?
