is my injen CAI taking in water?? or is my exhaust?

This never had happen before but i have recent installed a new exhaust system (Greddy evo 2 catback) and everything was fine until i drive my car (dc5s) in the rain and going over a small puddle of water.. the engine or the car starts to vibrate and acceleration seems to slowly response(lose power) and engine will make a funny noise and this will stop a few meters away and everything returns to normal.. then it'll start to happen again if i drive over another small puddle.. is my Injen CAI taking in water or is it my new exhaust system?? becuz this problem never happen to me before with just the CAI..

sounds EXACTLY like the problem i just started getting last week after i got my after market exhaust installed and started trying in the rain. Dry days are fine but when the rain comes down its gg :(

read this thread mate

http://www.ozhonda.com/forum/showthread.php?t=80848

yahh maybe its the exhaust.. but why?? lol..

hmmm, it sounds worrying cause i've got a mate who got his engine halted as his CAI sucked in water when there was a flood. It'll be good to have a check dude

yahh im having it check sometime today.. i'll let you guys know of the results.. im planning to replace my injen CAI cuz its worry me sometime...

Its your exhaust dude this has been covered majorly in all different honda forums. Same thing happened to me when i installed my Buddyclub PRO spec III. It seems to be the exhaust expanding and contracting when wet causing it to vibrate. Its not the CAI.

what is the solution to it then?? vibrate and lost of power? and makes funny engine noise??

no fixes just yet :(

i had my intake and exhaust checked today.. everything seems to be ok.. they cant find anything wrong with it.. im getting "INJEN HYDRO SHIELD" for my intake..hopefully it'll fixes it.. i'll let you guys know of the outcome..

nps let me know how u go mate

What a f**king weird ass problem!!!

its 100% not the cold air intake
adrian (toda) drove my car thru massive puddles trying to get this problem and could not replicate it

u basically have to have the entire cai submerged in water whilst on the throttle to cause damage

the problem still happens without a cai i tested it numerous times...

please refer to the long thread

the "INJEN HYDRO SHIELD" will eliminate the CAI problem, even those i never had this problem prior to my new exhaust.. ><

i emailed GReddy, here is their respone to this problem... i covered my intake with ""INJEN HYDRO SHIELD"" fingers cross..

PS: plz +rep me if the respone provided helps.. i want to sell some stuff >< thanks

Thank you for your interest in Greddy Products. We apologize for the delayed response. Did you modify your air intake? If so, are you using a Cold Air Intake? If you are, there is your problem, your intake is sucking in rain water. Change back to stock or Short Ram Intake during rainy season. If this does not apply to you please emails or call us 949-588-8300.

What do you mean CAI? You upgraded your intake, so it "flows" better, you upgraded your exhaust, now your intake breaths even better. Look at it this way, to breath properly, you need to be able to exhale as well.

Thanks for the advice, yes I have an injen CAI but why hasn’t this problem occurred when I only have the CAI?? Is it because the exhaust requires more suction?? Thanks guys,.

asking for rep... lol.

dont be shy to give..

You didn't really do much to receive it.

As has been discussed several times, in several threads (And shown by Adrian @ Toda) the injen intake dose not get affected by water.

Do you think that maybe GReddy are blaming a differant modification so as to take the blame of there product.

The hydro shield is "water resistant", not water proof. If there is heavy rain, puddles etc, it wont keep all of the water off the filter.

if this doesnt work then im going change me intake.. i'll let you guys know if it work for me..

- have you checked if it happens in dry weather?
- have you checked your pod filter after driving in the wet to see if it is damp? and how damp it is?
- hydroshield is pretty useless in repelling water, it does for moisture and puney water droplets but if alot more comes onto it, it gets soaked.
- you checked all your sensors are plugged in?

Definitely not your intake, I have an injen CAI no problem... I then had a cat back toda exhaust put on.. it was raining the day it was installed... I drove home not problem, drove to the shops later that night and it felt like the exhaust hit the floor of the car and was vibrating the drivers seat (but no lose in power)... happened again once more and never again since.

I put it down to the exhaust settling in.

but if you think about it.. the exhaust flows one way only.. so i think its the intake cuz exhaust couldn’t have possibly make the engine jerky.. and lost of power.. would it be possible that the exhaust has made the CAI sucks harder and therefore sucks water into the engine?? anywayz i will let you guys know of the outcome.

Fairly certian it wouldnt... I have a Toda header and a high flow cat installed as well now... not a problem...

I'm still struggling to see how a cat back is going to make the intake "suck harder".

Have you got OEM or aftermarket headers? I know that with the AUDM DC5R headers, the cat is set to a differant angle to the JDM headers... so JDM cat backs don't mate up to the AUDM cat correctly... and you get an exhuast leak... I never had vibrations before putting my JDM headers on.

AUDM Type S has differant headers to the AUDM Type R... so not sure if this is a problem.

I see you have bought some aftermarket headers... any updates on this problem?

No not yet, havent been raining yet.. i now have headers and Hydro Shield..

i no longer have this problem., this is what i have done..

1. I covered my CAI with a Hydro Shield
2. I replaced my OEM header

:)

im thinking the issue is the aftermarket headers!

i think its the aftermarket exhaust butting up to stock cat and stock headers. Because the way i see it after looking at this and the other thread is everyone that has a aftermarket exhaust installed is having this problem BUT everyone else that has the aftermarket headers + cat + exhaust they dont have it. Please correct me if im wrong if u have aftermarket headers + cat + exhaust and are getting the problem

Have you got CAI installed?? if yes then get the HydroShield.. I no longer have this problem.. but i have also replaced my headers..

i got a gruppe m intake. I dont think the hyroshield fixed ur problem, i do however think ur headers fixed the problem

yeahh.. i got INJEN CAI.. is it possible for gruppe m intake to take in water?? well maybe a new headers will fix the problem.

guys im looking for a hydroshield for my dc5r, what part/model number should i get?

CAI suck water in the engine, that all you got from CAI when it rain !!
