Air intake?
 
So there's a Hyundai genesis around town and it's got some kind of air intake I've been told that its the air intake... It has a very distinct sound. Almost like a hissing. It revs up then hisses and then revs ups and hisses, etc. anybody know what this may be or if its even an intake or something else?...

sounds like an intake, why do you care?

The_W_95 10-25-2012 10:00 PM

It sounds amazing and wanted to know exactly wat it was and if there was one for an e46

All cars have intake...
Cold Air intake will typically hiss, then rev.
Not rev then hiss.....sounds like a blow off the way you're describing it.

I just don't know much about intakes so I figured I'd ask on here

It is probably a turbo blow off valve. It releases the boost pressure when you let off the gas. Most oem ones are very quiet,but you can R!ce it up...I mean change it out to make different sounds. Doing that is an attempt to mimic serious high performance high boost engines.

Genesis turbo BOV. Nothing to write home about. And no...you can't get one for your bone stock e46.

Nice....I was going to suggest recording the BOV noise on to all 99 tracks of a CD-R...with the radio up really loud you could time it just right with the track skip button as you let off the accelerator.

Why would you put a fake one on?!?! That's just asking for it

I asked what it was not a fake one. Just saying

It's the turbo blow off valve.
Someone had a genesis at my last autocross and it sounded like it was eating squirrels. Awesome.
