I can hear whistling coming from my engine from inside the car, windows up radio off. I checked near the intake and there is this pipe that feeds air into the air box it was sticking out a bit revealing the foam that seals the link between the air box and pipe. It only happens when I hit the gas and when I was in park when my engine was still cold. Anyone know what's up?

 

I bet it's a squirrel

 

i have a little whistling sound too when i hit the gas and at certain rpm

i wonder what it is...

 

Thing is I never noticed it before...

 

normal, it is something that makes the car sound like it has a high performance intake, you should search sometime. many people have been pondering it before.

 

 

but a SRI or CAI and that sound gets louder.. I love it..

 

The whistling sound is probably coming from your thottle body.

 

sounds like a SC lol

 

whistling's normal. scion made it so that it'll kinda sound like a s/c. a cai will make it even more apparent.

 

my 'whistle' is very prominent with my injen cai around 28mph, and 65 mph.

 

it depends on your rpm and how hard you're on the throttle. not the speed

 

If you think that's weird, put a short-ram on. After about 4k under WOT, the engine sounds like it has a leaf blower powered by Jesus attached to the throttle body.

 

I dont think squirrels whistle but chip-monks do havent you seen the Alvin and the Chipmonks!!

 

I pushed in the pipe into the air box and now the noise is gone. Does it hurt not to have a noise? I knew it was already talked about, I was just worried because it was something not there in the morning.

 

Good luck with those squirrels or chipmunks watever they are. LOL

 

Probably CAI....i think!!

 

Gremlins....

 

that made my day ahahahahaha,

 

oh man i hope it aint gremlins. lol
