Ok I know some of you guys think that some ducts are going to give you forced induction, I am not trying to be a a-hole but here is an example of ram air and its benefits. I ride a ZX-7r and if you look at the link you'll see the huge ram air ducts on the front fairing

Dyno tests have shown those huge ducts do nothing until 150mph, then it's about a 5 hp gain. So keep that in mind before you guys start cutting up cars and running duct work through it.
