This is why you've never, ever heard of a Boxster hydrolocking.

Interesting. I've never seen anyone mention hydrolock concerns. I certainly never mentioned it in my earlier post. I do believe ingesting large amounts of cold water is bad for Boxster engines but that is a different issue than hydrolock. Of course it wouldn't take much water to hydrolock an 11:1 motor:

From K&N
"Are Cold Air Intakes safe in the rain?
NO CAR should ever be operated during flooding. Unlike short ram intakes, cold air intakes draw air from a relatively low position. Your vehicle can technically ingest water from rain puddles, streams, floods, etc if your car is lowered or the water is deep enough, and damage your engine. To prevent this, you could install the appropriate sized AEM Bypass valve onto your Porsche 911’s AEM or X3 Cold Air Intake, however, we instead recommend switching to your vehicles stock intake system if you anticipate driving through flood conditions. K&N FIPK Intakes do not require bypass valves since their design is higher than AEM and X3, and are relatively safe from water ingestion."
Yes, water ingestion is a very real potential problem with a modified air intake system especially on a Boxster, which is why our stock intake is so contorted. Choose wisely.
