I have installed the AiRaid intake and throttle body spacer. It now Growls and whistles! </div></BLOCKQUOTE>
Whistles? is that from the throttle body spacer? Did you notice a difference with the spacer? If it does whistle that would suggest a leak.

A whistle is not a leak. One site even mentions the whistle "means it's working".

Originally, I was thinking about getting the throttle body spacer when my H3 comes. But I don't want a whistling sound.
I'll probably just do the cold air intake and exhaust.
