CAI Bypass Valve
Well, I finally found a bypass valve for my AEM CAI. I've heard that you need to cut the pipe in order to install this. Has anyone done this before? Any advice would be much appreciated!
Yes, you have to cut your pipe with the AEM. You have to cut out like a 2-3" section of pipe, the bypass valve comes with instructions and pictures. When I installed it on my Injen intake, I just put it in between 2 pipes instead of using the coupler.

I cut mine.. not for the bypass valve, but to do a little customzing 
All you need to do is hit it with a hack saw. Even a dremel with a cutting bit will do. The cut doesnt have to be perfectly straigt, since the sleeve/bypass valve will be covering the edges. And be sure to wash out all the metal shavings inside the intake pipe before you reinstall it. All that metal shavings inside your motor isnt a good thing

Also might want to put some paint or clear coat over the unfinished metal to prevent it from rusting.

I heard a rumor.......
Is it true that AEM makes the Nismo CAI? If so, how many other Nismo products are created by other companies?
And, if this is the case, then Nismo is REALLY ripping people off.

Once aluminum is placed in an oxygen environment it builds a protective layer of oxidation. Although this layer plays havoc during any welding process, it does protect the aluminum from many outside elements.
I installed the bypass valve last week. It took me a whole... 2 minutes. All I did was remove the first connecting sleeve and replace it with the bypass valve. No cutting needed. I'll post pics up as soon as I get a chance.

I have a Sedan and I installed the Injen intake the filter itself is pretty much hidden its not visible from the outside unless it look at it very very closely. How can your filter get in water, the bottom is covered up and the car sits bout 10 inchs off the ground. Maybe in the coupe you can see the filter through the front bumper but the sedan is pretty much hidden in the far right corner of the bumper
Reguardless, the only way to suck up enough water to hurt anything is if you submerge the filter, and to do that you have to drive through a puddle like a foot deep. And if you're doing that you're an idiot anyway.
