You would pretty much have to have the entire filter completely submerged to suck water into the engine. For a test of this, take a shop vac, a CAI filter and a bucket of water. Attach the filter to the shop vac and turn it on. Slowly stick the filter into the water - you won't suck water until it can't suck air any longer. As long as you aren't going mud bogging or driving down flooded roads, you should be fine.

I've never had a problem, in really Humid/misty times water gets every ware. So if you are doing hrs in the rain it not a bad idea to make sure your CAI isn't soaked

If you are that worried you can add an air bypass valve but its not necessary.

No need to worry about water. The wheel well will protect the filter. Driven my car (with CAI) through a huge puddle. Car bogged down a bit but kept going. Never had a problem with it

In regards to the shop vac idea, it would give you a pretty accurate interpretation but wouldn't the car suck in more air than a shop vac? I'm not too sure about it because I haven't felt the suction the car makes through the throttle body creates

I never had a problem with it. Drove through rain and puddles. Only bogged down once.

I had a pretty powerful shop vac I tried this on before putting my CAI on my Speed 6 - the principle still holds unless you've got a really weak vacuum - air is easier to suck through a porous material than water so it will take the air before water. If you were aiming a high pressure hose at the filter so that it would pass through that might change things up, but wouldn't really be a realistic test.

You can't blow a motor with water? You'd hydrolock it though. You might have have driven through a lake maybe? Or not tightened a clamp on your CAI? I've hosed down my engine (not power washed) and it works stunningly well still.

+1! Hahah

Oh okay, you still get an accurate test out of it regardless though. And the filter is like a foot or a foot and a half in the air so unless you're driving through a flood and had your wheel well off then that would be a more accurate interpretation of the shop vac test lol

You can blow it , If ur going 40 and under no prob , but when ur driving fast and it sucks up the water can't compress in the cylinders so it can bend the rods that's what happened ether way bought a brand new motor

Rain wont hurt it but if your going to wash your car, watch where you spray up front. I put saran wrap and a couple of towels in front and below the filter.

My Mom bent a rod on my civic si just driving over a deep puddle just passed my driveway. The cai positioned the air filter just below the bumper.

I wouldn't drive through a puddle at 20+... Damn that's gotta suck. Good to hear you got a new motor though. Maybe the positioning and the protection of the filter itself is what can make the difference. I have a friend with a pretty low Acura. His CAI is literally 3 inches from the floor.

Lol. Buddy had the same thing happen on his turbo civic. Hit a puddle, sucked in water bang! Put the rod through the side of the block.

OP,

As others have said, you'll be fine driving in the rain with a SR CAI. I don't suggest driving fast through deep puddles, but I also don't suggest that with any car. Just use your common sense on what's deep and what's fast, and you'll be more than okay!

I know I am not the only one thinking this and I have seen this many times, (NEED PICTURES).
