Dude it's cool,think about it. You've seen what the snorkel connected to correct? Rain would have to be shooting from a 90 degree angle to get in the intake system. Even then it has a uphill climb and has to get past the air filter......highly unlikely.

*No aftermarket intake kit has a snorkel and air is brought in from almost the same location as a desnorkeled system. I hope that makes sense.

Your car, and all cars for that matter, ingests a certain amount of water when you drive in the rain. Even in a deluge, you won't suck in enough to harm your engine. It's not until you drive through water deep enough to submerge the intake that you need to worry.

I don't know about the technical aspects, but I have been driving in rain for 3 years now desnorkeled and have not had any problems. Hope this helps!

However, if you desnorkel, you must not drive your car through an automated car wash (which you probably wouldn't do anyway but is worth mentioning) and you should not shoot your hose into the intake when washing the car in the future.

And one more thing... don't flick your cigarette butt out the driver's side window whilst driving down the road or it could be sucked into the intake and cause a fire.

the airfilter should prevent hydrolock in most situations.

What's hydrolock?

By the looks of it to me. It would be easier for moisture to get into the intake w/the snorkle than w/o. Not saying it is something that can happen really either way in my opinion.

I was thinking that as well. The snorkel tube could act as a tub to hold water.

Oh well,if you really want to make sure you don't get any water in there just buy the update louvre that has the bottom two fins(?) connected not allowing anything in through the bottom.

In automotive terminology, a hydrolock (short for hydraulic lock) is the immobilization of an engine's pistons by a liquid (usually water, hence the prefix "hydro-"). Hydrolocking occurs when liquid fills a cylinder on the intake stroke and, due to the incompressibility of a liquid, makes the compression stroke impossible. This, in turn, prevents the entire engine from turning, and can cause significant engine damage if one attempts to forcibly turn over or start the engine. Typically, connecting rods will be bent, making the engine uneconomical to repair.

It is relatively common when driving through floods, either where the water is above the level of the air intake or the vehicle's speed is excessive, creating a tall bow wave.

Hydrolocking is often a concern when consumers modify their engines with aftermarket intake systems (e.g. Cold air intake). A cold air intake typically locates the filter near the bottom of the engine compartment to gain access to colder air, which can also increase its chances of ingesting water should it be submerged.

Another reason for it to occur is in the event of the head gasket cracking or "blowing", which causes the radiator coolant to mix inside the combustion chamber.

Hydro lock is when enough uncompressible liquid, usually water, enters the cylinders to prevent the pistons from completing the compression stroke. Unfortunately, some other parts often continue their cycles in spite of the blocked pistons.

I was driving from Louisville to Knoxville on Sunday when I encountered a large downpour. All was fine.

Nothing good. Liquids are incompressible. If you suck water all the way into the cylinder, your pistons will try (and fail) to compress the water.

Expensive things will bend and break.

I've been skeptical of doing this "mod" but, yesterday I decided to take off my side vent and check it out. I had just got home and driven through the rain. Took off my side vent to discover that it was dry inside anyway. Just looking at that "snorkel" doesn't appear it does much of anything. A tube with a bowl on the end of it.

So, I desnorkeled since it's completely reversible anyway. Love the sound and if I were to get an EVO intake, the snorkel wouldn't be present anyway. I think it was put there as a safety precaution for Porsche so, they they didn't have to replace an engine if it were potentially damaged by their design.

Don't spray the garden hose in there when washing it, I don't do that anyway.
