Example of air leak in the air duct assembly.


This bulletin applies to all Subaru models equipped with a turbocharger. The customer may comment about an air pressure leak or air rushing-type noise under boost conditions.

The intake duct leading from the intercooler to the throttle body may be out of position. The cases have been seen on 2012 Impreza WRX models as well as other models. Check for proper positioning and re-install the clamp.
