Hello there, just saw this item on eBay, it apparently increases your performance, its basically a non-electronic intake fan... also i think it goes between your Air filter Box and Engine (Inlet manifold?) rather then in front of the Air intake as i would have thought.
one of my friends bought one for his Ford Fiesta 1.6 and he claims he notices a difference. Logically isn't this just clogging up the passage for the air?
what are your thoughts or Experiences?
