Search. IMO, they are a waste of money.

 

..waste of money

 

They're a pretty big waste of money regardless of what engine they're on. All they can possibly do is increase the volume of air in the plenum; without increasing flow through the plenum, you're really not accomplishing much... and don't even get me started on those ones that "twist" the air or whatever you want to call it to "increase velocity".
