hissing air cleaner

I've heard other people talking about how their engine hisses with an open element, and was wondering if this is normal and of there is a way to stop it.

oh yeah mine hisses too

It's norman. Just the engine sucking in air. I think it's a pretty cool sound myself.

I get this too. It's funny because at startup it sounds like it's sucking it through my air conditioning vents on the interior. If you have a loud exhaust like a flowmaster like I do, you won't hear it at all while driving.

Mine hisses like a bitch. Personally I don't like it; sounds like a giant vacuum leak.
