The Stillen CAI was the first mod I did to my 05 6mt and didn't notice any difference in sound or performance. There might of been a few extra ponies up top but I couldn't tell since I was still breaking in the motor. However, once I put the ztube on got a lot more noise. You can hear the air being sucked in the motor and a beter growl from the motor itself. To be honest, I think you can get the same effect with a k&n filter minus all the sound resonators around the stock air box and a ztube. That would save you over $100 for other mods.
One more thing about the Stillen - it's a b_tch to get the bottom bolt in. The easist thing would be to leave it off but I was determined to get it in.

The spacer that people are talking about is at the throttle of the engine. Is this correct?? I really like the sound of the engine with the spacer and z-tube.

I went with the Stillen because I wanted to keep everything "stock" looking. To the untrained eye, it's difficult to notice the Stillen airbox. It's a bit louder than the stock airbox but adding the Z-tube really makes a big difference in the sound.
I highly recommend the Stillen if you prefer to keep thing low-key. My only concern is removing the big K&N cone filter when it comes time to clean it. The whole airbox has to come out and there's a bolt at the bottom that was a pain to install.
