    You need a tool called a "boost leak tester". You will pump air into your intake track and listen for leaks or spray soapy water to get a visual of the leak.
    A quick Google search will yield many sites to buy one premade and instructions to make one yourself if that's your fancy.

    But until then, get a screwdriver and tighten every hose clamp from the air-box to the throttle body. Dont torque the crap out of it, just a sure hand tight.

    Here's a good link to a DIY one. A bit on the fancy side, but you can scale it to your needs:
