This has only started to happen in the last month or so. When the car is turned off, right after the motor completely stops, I hear a very loud 'sucking' or 'whooshing' sound for about two seconds. It's always just 2 seconds. Sounds like some type of vacuum pressure sound. Doesn't matter if A/C has been used or not. I have an '03 CL-S with the CT Icebox installed. Thanks everyone !!!

I don't own a icebox but i'm pretty sure it's your source.. Every other intake I've own makes that sound when the car is turned off.

It's not a CAI, it's a IceBox..


Sounds like a commercial..

oneilc

Jonesi

Nothing, it's working just fine..

6speedctrlfreak

oh OK thanks guys but is there any reason why sometimes it happens and sometimes it don't ??

From the threads that I have read ----
of the dozens of questions on these boards about a sucking and or whistling sound, each of those people recently put on a CAI.

I porbably had that same problem, I was told by my dealer it was from the dual mass flyhweel, it's heavy and when you turn your car off the thing is still spining and then it shuts off, that's what they told me, try holding down your clutch and turn off. see if that helps...

I've had that noise ever since I've installed the icebox. Happens every single time I turn off the car. Maybe you just haven't noticed it until now?

I hear a similar sound when I shut down my car. I heard before with just the CT intake and now it's a little loader with CT S/C and intake. I don't think there's anything to worry about.

Chaptorial

Have the same sound at shut off. Thanks to the icebox.

DPOLICH

I have had the same sound since the car was new without the Icebox. Same sound exists today after installing the Icebox. The Icebox had no effect on this sound whatsoever.

labmeister

My car does the same thing and I don't have a CAI installed. It started about a month ago or, at least, that's when I started noticing it.

Chaptorial

Did your CL already come with an aftermarket intake? I definitely didn't have that pronounced a sucking sound when I was stock.

Jimmbbo

Have the same sound... lifted the hood while a friend shut the engine down.... 'tis the CAI...

Cheers!

You probably just haven't noticed it until now. Just about all types of air intake systems produce that noise when you turn off the engine.

Red-CL

It's the Icebox.

Mine does it too.

BC2G

yea before i had the CAI it whined when i shut it off, after the intake its a lot louder though

shinybluecls

i've had both aem cai and comptech icebox, both hiss when u turn off the car. however the comptech has a much quieter hiss, much to my liking =)

These engines have 10:1 compression. Your hearing the blow by that occurs when one of the pistons is on the compression stroke. Normal.

The same thing happens in my car and I do not have a CAI installed. Although, I have the K&N drop-in.

Ditto - mine is much more noticeable with the K&N filter in, although it's also noticeable stock.
