Cobb SF intake Leaking Air?

I just installed my Cobb sf intake. But when I changed gear around 3000 RPM, I could hear an air leaking sound from the intake. It happens when I depress the clutch pedal. The leaking air sound is similar to the sound that you open the soda bottle. I had double check that everything is installed in correct way. could someone help me to figure out what happen? Is that normal?Is it the factory BOV Sound? Why I don't hear it when I use the Factory Intake System?Thanks a lot

Normal BOV sound. It's much louder usually with an aftermarket intake. You probably didn't notice it before with the factory intake.
