slight whistle sound?

jhauschild · 08-29-2008, 10:57 PM

This isn't a real big deal, but I figured that I would ask any how. Since I bought my Spyder there has been a slight whistle sound from the intake area when I lightly accelerate. It isn't there at idle and when I give'er. Any Ideas.?

What you are hearing is most likely the sound of the air charge going over the butterfly valve. Totally normal. Its just like when we whistle. small concentrated air going over a curved surface that creates a sound charge. It's done it on every car I've ever put an intake on.

Its the type of thing manufacturers try to cut out with the stock airboxes.
