weird whistling noise at 3200rpms?
I have an 09 5spd with about 6K on it. I have the Injen CAI converted to short ram and an hks hi power axleback.
i noticed that at around 3200rpms when i shift, or when im accelerating i hear this weird whistling noise, and its not the "injen whistle" that doesnt come until about 5Krpms at WOT. this whistle is liek a high pitched quiet whistle. i checked around the intake to make sure there was no air leaks and everything seems fine. anyone have any ideas? |
yea there`s a leak somewhere, do u have a check engine light on??
|
my stock intake has always done that..... I wouldn't be too worried.
|
My car does that as well even with the stock intake. Its nothing to worry about.
|
it has to be your CAI, dont believe me? Then swap out your CAI and place your stock intake to see...other than that it could be your speakers..depending on if you have an aftermarket sound system. I know a couple of people who had installed there wires with different frequencies and resulted with a whistling sound every time they accelerated.
|
i have the injen CAI intake too and i have the same noise. Idk what it is but Ive had it for like two years with no problems or check engine light. I think its normal, it depends on the position of the throttle because mine dosent do it at full throttle only at about half.
|
mmm i guess its normal
|
I am surprised this hasnt been locked yet. This is probably the most common question ever asked on this forum.. just not in a while due to people already seeing previous threads.
The stock intake does it... a CAI makes it louder. Its normal |
This is from a very quick search using hiss or whistle in the keyword.. there were many more valid hits than that. The search is your friend

i've got an 09 boosted tc and does that all the time around those rpms nothing to worry about i guess..

its normal its a whistle as a result of air hitting your throttle body in the position it is, this is the way our intake was designed and the cai and short rams make it louder short ram especially
|
my friend had the same issue, turned out to be a defective muffler lol
|
I had the same issue with my injen. it just means it is working for you. haha jk I dont know but mine did it all the time.
|
My old civic, with the ac on, did this around 3k rpms because of the intake. I liked hearing it!
