Injen intakes vs Rain
 

These injen intakes are gonna be the death of me man... I can not for the life of me drive my Z when it's raining. I've done countless research and seems like my last resort is to upgrade to stillen g3...

Has anyone came up with any recent solutions? I heard hydroshield is complete ***, so don't bother recommending that unless the company has actually put effort in their product and is working.

What's the problem, getting wet?

i have Injen too and haven't had a problem with them at all other than the airflow is a bit more turbulent than the Stillen setup so it is louder, but that's not the kind of issue you're talking about.

Gets too wet to the point my car jumps, stalls, and eventually will turn off. On 7AT as well. If I go over ANY puddle, CEL will turn on and the car will slow down and won't run.

Is there space to use the AEM bypass valves?

Kick it to the curb and use something else. No way would I put up with that.

Do you have some pics of the intake installed on your car? There doesn't seem to be any other members reporting this problem with the Injen setup.

I attached two pictures. They were from my phone but I don't have any of the filters

I've also heard about others with the same problem as me on this forum but it was years back

Seems like one member made up a workaround, but it seems like a switch to a Stillen or Maf hoses/drop-ins will be your only guarantee.

MAF hoses would fix the issue you think?

Yes, going back to the stock airboxes with maf hoses and drop-ins would solve this.

He said mad hoses/drop ins meaning going back to oem boxes and changing to the silicone intake hoses behind it. So yes will definitely fix your issue since it is basically OEM.

Beat me to it

Wow I've got nothing like that at all, and I even took the cover off the fang vents and removed the vertical pieces that block that compartment off around the crash foam.

I assume you have all the underside pans on? Can't think of anything else that would cause that. Water is seriously getting in there somewhere.

I had the Stillen on at one point too. It switched back to Injen..

Maybe try a KN dry charger wrap

why cant you drive when its raining?

Why can't you read the thread?

do you not have fender liners?

The way the intakes are made, it drips water from above down onto them. i've had the same issue in heavy rain

to do what he is saying you realize how much water has to be getting on those fitlers

somethings not adding up

I had a cold air intake right at the bottom from Under bumper area on my eclipse and I used a Air filter waterproof "sock" and it worked wonders, Never had an issue swalling water and I went through pretty big puddles, mind you I still slowed down etc when going through puddles, but Rain, bring it on I never had an issue, even in intense rain storms etc and I was driving it in Winter too, with all the icing rain etc you can bring.

Have been caught in heavy thunder storms a few times and never had an issue with my Injens. Been on my ride since 2010.

bingo

Have a link to those? Gonna need some sort of way to prevent this pretty soon.

Not much water gets on them and it still happens every so often. Not even low to the ground either (stock springs). 100% chance after going over a puddle I'll be getting the issues, but even if it's just driving, it will happen e.g. driving for 30 minutes it'll happen.

If I'm driving for about 10 minutes, then nothing happens.

^^^ I had the same issue. Parked a couple of hours in the rain and I even still had an OEM hood. When I started the car, the RPM couldn't go higher than 3k. The car jerked and died. They do sound louder than Stillen G3 tho.

It hardly rain in SoCal but this still unacceptable so I switched to G3.


All fender liners and under shroud were perfectly installed.

Is G3 the better option? Might have to get rid of my injen and get G3, but then I'd have to put down more money on a retune... :|

Do you still have your plastic fender panels that protect it from waterpuddles or rain? If your car is lowered you be in danger when driving to even ankle deep floods. Water in your engine spells disaster.

I believe I do, not 100% sure. I did have my splash shield on but it didn't do any good so I took it off. And luckily it isn't lowered, but I've been wanting to lower it but can't due to this reason

They're called "pre-filter" or "hydro shields" etc. and most companies make them and call it their own personal names. Injen has some, K&N, AEM etc. Its meant to prevent large amount of humidity to reach your filter and "water clog" it to the point your engine would be starving for air, thus, preventing "water bogging" your engine. its not perfect and not meant to be an underwater snorkel like some people found out, but it enables you to drive normally without having issues in storms or winter etc.

Ah, the hydroshields... I read they are absolute **** for your car thats why I'm trying to stay away from it

I never had an issue with mine and it worked as advertised, I did the water hose test and it worked...I was actually impressed by it...;)

I guess your other option is to ensure you have a custom made "3 face splash shield (front/sides/bottom" designed for your interior bumper area where your filter will reside so that you don't have water splashing on your filter or the valve safety the guys are talking about, I heard that works too.

Another plus 1 for the Hydroshields.

Been driving in the rain without issue. I had been wary since I have an aftermarket front with vents that open up directly to the intakes.

I also tested them like Karnak did prior to install and was equally impressed.

The Injens or AEMs were my only long tube options and happy I stuck with the Injens and shields.
