I was very skeptical about the addition of a CAI, especially since I already had a drop in K&N filter.
I have found a different experience with my CAI than DanRealtor, however, I don't believe the installation of the DUB CAI would of made as much of an impact without having headers, Free Flow cats, & Cat Back system. If I would of installed the CAI first or second I don't think I would of realized the power gains that were specific to that mod. With the other exhaust mods in place, my bottleneck was getting the air in.
PS NO Flames!
Also, a good CAI is sealed off from the engine compartment as with the DUB or Volant & a few others. You will see many that have a cone shaped filter that sit in the engine compartment and pull the hor air in from under the hood. These systems may be less restrictive then the stock filter box but at least the stock filter box is sealed off from the engine compartment and pulls in cooler air from down below. I can understand why many people do not see a performance gain if they buy a CAI that pulls hot air from the engine compartment. In that case, you would be better off with a drop in k&N filter that pulls in cooler denser air from down below.
This pulls hot air from the engine compartment:
This is sealed off from the engine compartment and pulls cool air from below:
this is also sealed from the engine department and pulls in cool air:
