I'm stumped. When I'm at about 3 grand driving down the road I hear a whistle sound coming from the engine? Any suggestions on what I can check or what might be causing it? It will sustain if I stay at about 3 grand.

Thank you!

 

sounds like your intake is just making the noise. if so, it's normal

 

^this, my CAI does the same thing.

 

lol. my stock intake box with K&N filter does this too, i wouldn't worry about it.

 

Great, I'm happy to hear I'm not alone. Thank you for your help!

 

Ya i was wondering the same thing, i keep hearing it but it didnt mechanically wrong. hopefully it goes away when i get my prm intake in the mail, if it will ever show up! one week so far is too long for an impatient person like myself

 

its your VTAK spooling.

 

if driven three s2000s. One with stock intake, one with aem intake, and one with no intake, not even a filter just open throttle body.... And they all did it. So your not alone at all.

 

Oh i thought it might have been my NNNNNNOOOOOOOOSSSSSSSS!!!!!

 

Its just the sound of the air passing by the throttle body plate. It'll whistle when its at the right angle. Ever Honda I've ever driven does it. An intake will just make the whistle louder since you remove much of the silencing.
