Yah you can deifnitely hear the CAI sucking in air...especially in the cooler temps.
You will probably notice a slight whistle when accelerating too.
In all reality the CAI's on our v6's are more for show/sound than performance. I'm sure there is some gain, but not enough to brag about...that's why the basic AM CAI or Bomz CAI on Ebay are good enough. Save the hundreds of dollars on the K&N's and BBK's and put it towards gears or a tuner
