OK guys so i started to do some welding and things and i though of a great idea..... Do my own Cold Air Intake since i got the perfect tubing... but in the middle of the process i started thinking since the CAI goes towards underneath the car.... WHAT PREVENTS WATER GETTING INTO THE INTAKE??? i called up 2 of my friends to check their intake.... one has a kind of foam looking thing between the pipe and the filter to prevent the water in.... the other doesn't have anything just the filter connected straight to the pipe....... i mean some of you guys have CAI right.... WHAT DOES IT HAVE TO PREVENT WATER TO GO IN???? HOW DOES THAT WORK??

What your friend has on his car is called a Bypass Valve or Bypass Filter. It doesn't really kick in unless your car is submerged in a good deal of water. I have an Injen CAI on my car and don't have any Bypass filter on it. Now I've gone through some deep standing water, and have had no problems. The cone for the CAI sits in the cavity underneath the right Headlight. The cavity is pretty good for not letting any water in. I had the same concerns as you when I first installed mine. I didn't want to damage the engine. One day after a few days of heavy rain and driving through DEEP water puddles, I popped the hood and tooko a look down in that cavity. It was a lil wet, but it wasn't wet enough to cause any major concern. Run your CAI to that cavity and you shouldn't have any problems. If your still a bit worried, you can purchase a bypass filter at O'Reilly's or AutoZone for about 10 or 15 bucks. Oh yeah, the puddles I drove through were REALLY DEEP. I live on the gulf coast of MS, and Katrina couldn't harm my ride. No worries man.

One guy I worked with told me he has a CAI and a SRI,he said depending on the season he would switch them back and forth.

get a k&n with a closed end... point the filter down so the closed end is parallel with the ground. water wont splashe up to easily... but dont extend the filter all the way to the bottom of the car, just enough so it is out of the engine compartment. made my own a few years back with stove piping from a hardware store. had the same worries, but just dont drive through a lake and you will be fine.

Yes... do invest in a BY PASS VALVE... they are about $50 and work great. They protect your car from hydro locking. Hydrolock is when your car sucks in water through the intake and then the MAF Sensor gets wet and makes your car start doing funny things. I have had this happen to me and trust me it is not fun. When it happens and you hit about 4,000+ RPM's the car will kinda buck and fall on its face nevermind the fact that you cant go over a certain MPH. Definitaly not worth it. Make sure you get this mod as well.
