Does Water and Air Intake Mix??
Bypass Explanation
I have the RRM CAI. I live in Portland, Oregon and haven't had any problems. It rains all the time here. All you need to do is use your head and don't go through big deep puddles.
The AEM Bypass Valve is used to protect the engine from hydro locking. Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle becomes submerged enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition. The distance of the filter from the road dictates the level of water that can cause damage. This distance varies with the vehicle ride height which is why there are no published numbers for this measurement. All AEM Cold Air Intakes are to be used with the splash shield that is originally installed on the vehicle for protection and performance. The removal of splash shields actually deteriorates performance by allowing hot pavement air in the vicinity of the filter and negates any positive pressure created in the air filter area when the vehicle is in motion. There are some instances where there is not enough room around the inlet pipe for adequate clearance of the Bypass Valve. In these cases a Short Ram system is offered or will be offered in the near future.

Don't bother with the by-pass . With my CAI I would need to go into a puddle about a 14-15 inch just for the water to get up to where the filter sits, then it would have to be fully submerged.
i had the bypass valve, the aem bypass valve that is. I think its a piece of shiet. Its only a piece of sponge, and some cheap *** rubber and they charge about 50 bucks for it. I mean come on people use your head, if you submerge your car into a huge puddle of water, what do you expect ? LOL Just like that guy said just get a sri, sri gives you a bit more torque, cai gives you more hp, whatever floats your boat go get it. I live in va and it rains like crazy over here, had my rrm intake on since february and i always drove in wet weather and haven't had one problem yet without the bypass valve on. So i took that piece of crap back which i never used and got my 50 bucks back! Also yes, you do lose some power with the bypass valve, since your sucking in hot air now because the cold air is now hitting the bypass valve then going into your engine. And yes for the winter, i would recommend that if you have a two piece intake set like the one from rrm make it a sri 8- )
