There are small holes that allow enough room with air pressures at freeway speed to reach the filter. The filter sucks the water in, it does not require momentum by the time the water reaches the filter with the amount of suction from the motors vacuum pulled when running, especially under a load. Water will seep through the filter. The info I provided you guys is based off of what actually happened, not some theory I have developed. I simply stated that water WILL get in to your motor with this CAI in the rain based off of something that actually happened to me although it is not enough to actually hydrolock. I'm not some noob on here with false information and so far every other post is about how I am wrong or how to fix it by spending more money etc etc. I am just letting you all know that the CAI provides no added benefit as the only reason this intake is making power is because it leans out the air fuel ratio due to the small tube by the MAF which tricks it not because of the added airflow. You guys can do or say what you wish I am not going against it. I am simply warning people that have rain in their areas. If my help is unwanted then by all means let me know and everyone can find out the hard way or you can take what someone with experience, training and a lot of education in the subject in to account. This will be my final post in this thread as I have nothing else to say to the matter at hand.

-clap-

well put! now I know exacty what will happen and how it happens

Even if you don't post/read this thread anymore, you just saved me $50 and helped me make a final decision on CAI/SRI :D

In fear of starting up the CAI-water debate again....

where is the design flaw coming from...?
is the water issue due to how any CAI is installed on the tc2?
or just how the Injen CAI is designed for the tc2?

or is this just entirely an issues with any CAI in general for any car?

SHHHH.... It's taboo!!
But I am pretty sure it's just an issue with any CAI in general because I think all CAI are away from the engine bay and lower, so that's why there's the risk of water, when compared to a SRI


But if other companies make CAI for the tC2 I'm almost 100% sure the filter will be in a similar place

ohh okay so regardless of whatever brand makes it...it'll still be an issue

...is the "big deal" as discussed in this thread just with the tc2 or does it happen quite often/just as risky with other cars?

A knowledgable individual who is no longer posting in this thread gave me some more info and I think I understand what's happening.

The issue Papa Bear is talking about is a result of the combination of the MAF sensor on the tC and the CAI. Change either one, you fix your problem.

1. The CAI filter, because of it's location, is going to get wet in the rain. Get the filter wet enough, water will gather inside. Normal with any CAI on any car.
2. The intake will suck in anything that gets past the filter (including the pooled water)
3. Scion went with an inexpensive, drop-in MAF sensor. This type is affected by water intrusion more than a protected (and more expensive) sensor.
4. SRI would eliminate the problem of soaking your filter.

What concerns me with both the Injen intake options is that it's not really improving airflow much, rather, it's manipulating the sensor (and thus the computer) to gain power. To me, this sounds like the best reason of all to hold off on the decision for an upgraded intake until TRD comes out with something.

that's actually my plan haha. I want to see what else is there to offer before I buy now.

I'm just trying to gather as much info as I can now, while doing my research and $$ saving.

thanks!

Ok they look cool and sound good. Do you guys feel that you got 200 bucks worth of actual performance or mpg gains? .

Honestly throttle response is great. Looks sweet. Sounds mean. But 200$ is just tough on a college student but still worth it imo
