Tightening of this connection is necessary in case of leakage and air suction (a hiss is heard through a hose about 60 cm long near the base of the case). Remove the air filter after marking and disconnecting the hoses, and tighten the throttle body nuts and bolts to the specified torque. If tightening does not work, then remove the damper body and replace the gasket (Ch. 4). Install the filter and connect the hoses.
