I love my K & N Typhoon CAI. If your worried about water you can use the K & N as a short ram as well, this way when it's in the heavy rain season you can run it as a short ram and when the weather gets better you can convert it back to a CAI. Here is a dark pic of my K & N as a short ram and one of it as a CAI:

How deep does the water have to be in order to suck it in? How long does it take to take the lower piece off? Can you let it hang while you are using the short ram?

 

You would have to submerge the entire filter to get it to suck up the water and it would take either around 12" or more of standing water or less depending on how it splashes or waves which could temporarily submerge the filter. The oil in the filter itself will repell most sprayed or splashed water, it has to become submerged to cause the engine to pull the water through the filter. Depending on the tools on hand it could take as little as 5 minutes to remove the lower pipe. However, if I come to this situation I will simply loosen the hose section that connects the two pipes and slide it down on the lower section and retighten it leaving the gap open so that it will breath through it instead of through the lower pipe and filter. There is a very slight chance that something could get sucked in through this gap, but it is extremely unlikely for something to get up into the engine compartment like that. There are bypass valves that were made to be the cure for CAI's sucking water up, but they actually say in the instructions that they can cause a loss in performance, especially in turbocharged cars (this is straight from AEM's bypass valves papers/instructions), that is why I don't use a bypass valve either.

 

Thanks. What if you put an outerwear filter cover over the gap when it is loosened. Just a thought . You would have to have it open on both ends, but it would stop almost anything that could damage the motor.

By the way I think I am going to get the K & N.

have fun with your straw....lol 3' ones look WAY better in my opinion, and prob work better too

 

That's a good idea and it would work just fine. Once the rubber hose section that joins the two pipes is moved down on the lower section, you could use the filter sock that comes with the K & N CAI and use one of the hose clamps to keep it on and keep it from getting sucked in. Just clamp the sock onto the end of the upper pipe and it can breath through it without letting anything else in but air.


The lower pipe is bolted in place at two different points, it isn't going anywhere unless you unbolt it.

 

The 3" CAI's do look better, but they also tend to have fitment and rubbing issues. The dyno results seem to favor the 2 1/2" K & N over the 3" CAI's. Besides, the turbo can only draw in as much as it openings size will allow and it isn't even as big as 2 1/2" anyway, so in this case size isn't much of a factor if any.

 

I used to cut the top out my air filters when I raced karts. Put a pre filter over it and got somewhat of a ram air effect. I never sucked anything in, and when karts would go off the track in front of you, they would throw a lot of dust and debree up.

Bruins03,

I will engoy my staw. I might even get a custom made crazy straw to put under the hood LOL.
