Heres the way i look at it: hydrolocking from a CAI doesnt happen that often, but is the extra 2 or 3 horsepower worth the the small chance that it will happen?

edit.. hyrdro lock happens.. read below posts lol
The way i see it is CAI's don't have any advantage over a short ram intake other than torque.
CAI's create a small bit more amount of torque compared to short ram intakes..
but on the other ram air style intakes will have a better hp increase at higher rpms compared to a CAI
we all know the 350z doesn't really gain that much power from an intake filter.. so why spend so much money on it..
The fact that a ram air style intake is much easier to assemble and disassemble is another reason why a CAI isn't really a good idea..
so the question is.. when comparing a CAI to a Ram air intake
if it cost more money, takes more time to install and clean, and doesn't give a higher horsepower rating.. why would you even want one
The only advantage a CAI has is a slight increase in torque

It happened to me. Parking lots are the worse. Plus i was living on an island with tropical weather. Hit a one foot or less puddle and the engine died. Injen CAI FTL luckily no engine damage just need new plugs. Honestly the CAI sounds cool but other than that it actually seemed to make me loose low end power. VQ engine BTW.
Other than that the inside of my plenum/throttle body looked like azz after running the injen for a year. I wouldn't suggest cone filters if there so much more effective why are they not OEM? I mean look at our stock airbox its not a cheap design like some I have seen.

i will never own a cai again.
Long story short:
-Cruising
-All of a sudden flash flood
-Cruising up hill
-Hill turned into a river
-Water though CAI
wait.....
i didnt hydrolock, granted i hit 6k trying to get out of the stalling engine.
BUT i did suck up enough cool water to touch my hot head and warped many many valves. Jumped time. Motor siezed. Screwed car. Cost more then it was worth to fix.
How i have z and couldn't be happier

I had an Injen CAI in my Z for 4 years. Not a single problem and live in Puerto Rico, here rains frequently my Z was daily driven 70miles round trip with it and the Injen sits low in the grille exposed. My Z has the engine plastic under tray I guess it helped a little but is a matter of taking care when driving in the rain.
A coworker on the other hand had a CAI on an Altima and in our parking lot his car shut down (I saw it and he though he has a submarine in the way he was driving) luckily for him it was a matter of taking the sparks draining the water and changing oil.
But as stated;
Is it worth the risk for a couple of horses?
I latter changed to a stock box/K&N drop in and bumper duct and power difference felt was -0- ,as matter of fact I felt better throttle response with the stock box.

You won't hydrolock the car driving in heavy rain.
You will hydrolock it due to driving through a big-*** puddle you didn't see caused by the heavy rain.
The extra HP is not worth the peace of mind.

Lol the chances of it happening are so slim, it doesn't even warrant discussion unless you live in a flood prone area. Like someone said earlier, even the CAI's in the Z sit 2-3 feet off the ground and you'd have to drive through a small pond to have it happen. Water splashing on the intake filter isn't going to hydrolock your motor...

the intake has to be submersed in water to hydrolock. Small amounts of water won't hurt...just think of a water injection system on cars.
I drove for 6+ years with a CAI on my accord that sat only 5" off the ground. I live in the country on dirt roads, indiana snow and hella rain in the spring. Never had a problem and put 287k miles on that car. (over 100k on that cai)
