The stock air induction hose is made of corrugated black rubber that restricts flow and introduces turbulence in the intake. Not only that, it doesn't seem very heat resistant -- we've seen stock induction hoses actually melt on the car!

This induction pipe is made of multi-ply heat-resistant (it can withstand up to 260 degrees!) silicone rubber for much better durability, plus a much smoother intake path. The result is a horsepower increase of 3-8 hp, depending on boost level and modifications.
