I replaced my alta air filter with this K&N filter and all I can say is that I love it. No more whistle or noises except for the sucking(or gulping) of air and whining of the supercharger.

I was experimenting awhile back with a old K&N Cone filter (I was trying different things to get rid of the whistle) that I had laying around and noticed that I liked the sound more then the foam filter so I decided to order a K&N that would be comparible in size to the foam filter. It is pretty damn cool sounding.

I have made alot of mods over the last month (Miltek, Detroit BPV and 15% pulley) so I am not sure if it is a combination of the mods but the car sounds pretty damn sweet right now.
