This question is to all H-town G members that have CAI's, either NISMO or Injen: What problems, if any have you all had with a true cai? We live in houston where it rains alot so I'm wondering if it will be a problem to upgrade to a true cai. I was looking to buy the Nismo intake cuz it has that bypass valve. I've tried searching through the forums but there just isn't enough info on the subject. Anyway, all info, pics,experiences and comparisons are appreciated.

thanx

[B]I have the injen c.a.i. I like it, do not love it though. I only had 1 problem with it. During a BAD rain storm, I went to pass another car, and all of a sudden, holy sh**, the car fell on its face. I could not go faster than 35 or so. I went right to jiffy lube and had the oil changed. I thought I sucked in water, but thank god, I did not!! I just let the car idle for 3 hours, and it was good as new. I did NOT have a bypass valve in!! I know I got really lucky. Now in the rain, I drive like a snail.

Dude, that is the worst picture I have ever seen!

 

I have the Stillen HiFlow AirBox connected to the 350Z intake tube. No problems with water!

 

I live in DFW where, like Houston, when it rains, it pours. I've had a CAI on my past two cars without bypass valves on either.

Hydrolock with a CAI is like HIV. Everyone thinks it's real easy to get and the slightest contact will screw you up, but it's just not true.

You have to like, almost COMPLETELY submerge the pipe in water in order to get hydrolock, not just take in a few drops of rain, or drive through a puddle. If you are frequently driving through masses of water that are more than like 8 inches deep, or like to drive real fast through 4 inch puddles to make a real big splash, then yeah, you probably need to go ahead and get yourself a bypass valve also. Otherwise don't worry about it, and drive sensibly through standing water - as you should do with or without the CAI.

 

Down pours aren't what hydrolock an engine. I've yet to see or hear of an example of hydrolock that was caused by driving in rain, even the heaviest of rain. It happens when you drive into standing water that is too deep, or drive into standing water too fast, jetting water up into the engine compartment or in our case the bumper where the CAI sits, submerging the CAI.

 

Well said and well executed.

 

I doubt that could happen. When I had my Injen CAI I drove (safely) in some very heavy rain at highway speeds with no problems whatsoever. Not to say I wasn't worried about it, but it was fine.
