Hi,

I'm not sure the dealer is correct. There were never any cooling problems with the Boxster, earlier cars, or not. Besides, this is the Engine Air Intake, it serves no purpose in cooling the engine whatever.

There were however issues with rain water entering the engine during driving in torrential rains and several cases where this was so severe as to hydro-lock and destroy the engine.

Porsche's response was to add a better drain to the ducting inside the intake and to add this lip to the exterior. With this lip, the water stacks up before entering the intake and the accumulated weight of it is heavier than the suction of the intake, so the water runs down the sheetmetal and away from the intake, not into the engine...

Happy Motoring!... Jim'99
