I know it's probably been answered befor but being a newbie I have trouble navigating the site for old threads...

I just picked up an 2012 Autumn LTZ. It makes a suckling sound when I accelerate. It sounds like it comes from the glove box area. I'm assuming it must come from the air quality system. Any definitive answers? I also have a KN Typhoon cold air intake. Can this cause extra noise? Any way to reduce the annoying noise?

Thanks!

...or is it the turbo and blow-off valve that I hear?

This used LTZ came with the Typhoon. I don't need the noise. I'll look around on Craigslist to try to find the stock air cleaner kit. Anyone looking for a Typhoon intake?
