There have been a few members having moisture issues from the Injen intakes that led to poor drivability in rainy or even very humid conditions. I did not, however, hear of any solutions found as most either decided to live with it or get a difference set of intakes.

it's why i drive around with stock boxes. the injens come on on sunny days if i'm at a show or something (i.e. they will never see the light of day ever again.)

Yeesh... that stinks.
I say ditch them for OEM airbox + high flow panel fitlers + smooth intake tubes, or if you really want an aftermarket intake, go with the Stillen G3's.

I have the AEM intakes and they sit around the same area as the injens. I have been pretty hesitant driving it in the rain. I have to get to work though, so I just bought the injen hydroshields. I will install them and report back with results.

I've driven through torrential downpours and the car is outside most of the time and have not had a single issue with my Stillen G3 intakes, very happy with them.

1) When the car is parked at at angle, as when the nose of the car is on an upward angle. For instance when washing the car on an inclined driveway. 2) Parking in the rain in a parking stall that places the front nose on an upward angle. Ever since then I now wash the car in the street on a flat surface. As far as the rain getting into the engine bay and dripping down on the top of the filters was another issue. As I cannot always get a flat surface to park on when it rains. As it turned out water was entering the hood/engine bay and running down to the tops of the air filters. I even tried to block those areas in the engine bay that have gapping holes fron the inner wheel well. I found that Injen when manufaturing their CAI that they were lucky that Nissan has a 1" in diamter hole cut in the under cover that is exactly positioned to flow air to the inside of the air filters. I plugged the hole with a rubber plug and covered up the gapping hole in the fender well only to discover the air flow and car was gasping for air. All of it was removed and back to square one as to why water only messed with the MAF when the car was parked in the rain or after a wash on my inclined driveway. The car did not get any water on the filter and MAF when its moving only when parked and water is running down the hood. Turns out Nissan did not do a good job manufacturing the gutters on the inside hood and fender. Then again they did not intend for the stock air box to be removed either. When the car is parked at an upward angle and water from washing the car or rain will seep downthese channels on the fender and make its way to the air filter causing the MAF to either cough very bad or worse put the car into limp mode. Solution was to take some black weather insulation with adhesive backing (home depot) and run it along the edge of the fender halfway down from the top of the head lamp to bottom of headlamp. Fixed! Sorry for the long winded but this bugged the crap out of me when it first occured after my install of the CAI and summer came along and washing the car in the (inclined) driveway. After the fix I got lazy and really thought it was just mine and the bro's Z and no one else was having this problem, maybe because they never wash their car on an inclined driveway or park their car on an inclined parking stall in the rain to have this happen. Glad I am not the only one having this issue. Btw I still have no regrets buying Injen as I still did not have to cut into my car to get the G3's to fit and accessing the air filters to clean (thru the inner wheel well) is alot easier than removing the bumper. Hope this helps. For those wanting to pick up some of the filter booties, I ordered some from Amazon and they double shipped me for two cars, so I have extras that I am willing to unload at a good price.

@ zforce, i thought the incline was the isolated problem. however the second time it was parked leveled in a parking spot, heavy rain for a day andafter inspection water did enter through the top part of the engine bay around headlights...maybe just amount of rain and time were the factors that caused it to happen again.

Happened once to me! But it has rained 20 times since with no problems. I remember driving through a big puddle when it happened so I really try to watch for that now.
Expecting rain for the rest of this week also!!

It might just be that even on a level surface and prolonged rain that water could seep down the headlight. I fixed mine with the weather stripping during the summer time and over the previous 2010 rainy season I have to guess that there was not enough of constant rain to cause it to choke and go into limp mode. So you may have proved that it even leaks on a level surface with substantial amount of rain pounding on the hood. I have had mine parked on a flat surface all day during the recent torrential down pour of rain we had here in Sacramento this last week and no problems what so ever. This was after the weather strip fix. You may want to just get the weather strip, it only takes a couple of minutes to lay it down. I sleep much better now. Another tip is to be careful when washing the car and spraying water on the inner fender well. I still spray but with low presure and done quickly rather than holding the hose in one spot for any long periods of time. |

The Injen Hydroshield booties might help when hitting big puddles with giving the filters a little help with absorbing the water and retaining it before it hits the filters and MAF. I may install the booties on the next oil change. |
