View Full Version : Avoiding Hydrolock CAI

I couldn't find an answer to my question via searching, so i figured i'd start a new thread.
Logically speaking, in order to hydrolock your CAI you need to pretty much submerge the entire thing to cut off all outside o2 and your baby then inhales water right?
so generally speaking if you had a smaller intake filter, it would get to the point of inhaling water far quicker than an over sized one. and if you have a bigger filter, its easier for the car to inhale air generally, so am i completely off base to buy this filter and breathe (no pun intended) easier when driving in intense rain(a common occurrence in ohio)?
as a size comparison little and big.
27 cm tall and 20 cm wide
20 cm by 20 cm
all in all i want to know would it be worth it to get the bigger/more pricy version of the CAI?
is bigger better?

Get the small one.

Youd have to inhale ALOT of water to hydrolock.

I honestly wouldnt worry about it.

so there is no benefit to getting a bigger filter? and the aem bypass valves are a waste of money?
sorry im paranoid and the last thing i want/need is to kill my ride.

Most people who run a true CAI house it in the drivers fender. If you put it here and remove (or cut) you inner fender liner you shouldnt have an issue.

I've been running my CAI in my inner fender for over 3 years with No problems, in some serious wet weather, anytime ive taken my filter off to check/clean it shes been dry as a bone and not even that dirty... and now that i think about I havent cleaned it for a while haha...Something to do tonite :)

i have a iceman cai that goes down next to the battery, then it curves behind the drivers fog light. and i've never had a problem.

though one day i was on the highway and it started pouring cats and dogs (you could barly see) lol.

i just took it easy and didn't accelerate it much till i got to school. i touched the filter after and it was really wet. but nothing happened to the motor. (happened to me like 3 times)

i guess in order for it to hydro lock, the filter has to be submerged.

as a side note, what size piping should i use?

You don't need to cut or remove the fender liner. If you do that you're going to get a lot more water on the filter. I've got mine run into the driver's side fender and it works fine. No problem with rain water. If you ran through deep water that submerged the filter then you'd stand a good chance of hydrolocking.

You could also put a smaller breather filter some where else in the piping and thus not have to worry about it nearly as much.

should i cut a hole for it or move my battery? i want the filter out of the compartment.

07-21-2010, 03:38 AM
There's a hole in inner structure already behind the battery. You can use that one or just enlarge it a bit. That's where I ran mine through.

should i just run a pipe the same size as the hole on my intake manifold or is there any benifit in running like a half inch bigger?

07-21-2010, 03:35 PM
just run the same size.
