Pretty typical. The corrugated Throttle Body to Intercooler hose is
blown on the underside. Run a finger there and I betcha you'll find a
tear. REeplace it ASAP, coz within days your car will stop running
altogether.

BTW, you have two choices: either an OEM crappy hose for $64 from a
dealer, which my chipped to 18psi of boost car was blowing once a year,
or
call TAP and for $115 get a heavy duty blue silicon one, which will end
this problem for good.
