Why waste the time to post? If you are worried about it turn the car off, as long as you are in neutral who cares... You will get a bigger argument here that you take your speed through car washes like that and not do it yourself.
Get an SRI and be done with it.
(hand) I take it you havent been to to many auto car washes lately have you.... You have to drive over a row of jets to get into most of them.

Too late.
If you are seriously that afraid of water getting past the filter, turn your engine off and leave it in neutral. At least with the engine off there will be no air moving through the filter. Those jets in the car washes barely have enough pressure to clean the grime off your wheels, let alone be able to supply steady enough stream of water that would effectively hydrolock your motor. Your being too paranoid, lay off the hash.
better to be paranoid then one of the tools that go puddle jumping and lock up their motor. (bang) I don't see this guy being one of those tools.
