Snakeoil?
 

or is THIS worth looking at?

nah, that's a valid concept. reduces underhood temps, supposedly reduces lag.

Vote = worth it....less heat in the engine bay more heat going out the exhaust(instead of into the intake).....Heat staying in the turbo theres something mathmatical about why hot air expands like it does and why people aren't putting turbos near the muffler area(besides lag and the few oddballs who have done this set up) Not worth a whole lot but deff helpable.
