My friend the other day told me about this thing he saw on commercial, it is a little propeller type thing that you put in the intake system to help increase the flow of air into the engine. I was wondering if this was just one of those POS things that infommercials are trying to sell??????

 

everyone says pos, though i dont know how many of them have actually tried it on their cars.
