I'm looking to boost my horsepower by adding a CAI. However, I have heard the little import cars with them and I cant stand the loud sucking sound that you hear outside the vehicle. I need to have it but I'm looking for one that isnt loud. Anybody have one that works well and is quiet. Any suggestions would be much appreciated. Thanks

 

I have the volant, I cant hear it at all. I gained about 8hp from it.

 

The K&N CAI isn't that bad at all. It gives the truck a deeper tone in the exaust.
