Injen cold air intake

SILVERKNIGHT7 · 04-12-2013, 11:33 PM

I just installed the Injens and love them! But, I do not recommened them for a daily driver. If you just drive your Z on sunny nice days like me don't look back. I washed my car the other day and shined a flashlight to look down at where the filters sit and there was a little bit of water. I can't imagine what would happen if I got caught in a big rain storm and hitting puddles. I have a buddy that has the stillens and he likes my injens better because the intake sound is louder and you can modify the fang vent covers on the facia to make it like ram air. Ive also notice cooler engine temps. Throttle response is better and engine revs smoother.

The answer to what happens if caught in a big rain storm is - nothing. Twice I got caught, it was raining sidways. I drove 17 miles home both times from work. Not one issue to speak of. Ive also driven in many other rain situations with no issue.. Also with the car washing. Water doesnt float so it wont magically raise up. A little water in the well means nothing. It'll drain out and thatll be that. Unless you burry your front end in the ocean you'll be fine and if water intake worries you that much. Get the mesh water shields,

Hey Romulus1, I appreciate you sharing your experiance with the injens in the rain. That makes me feel a little less worried about it. I understand water doesn't "magically" rise up. I was just sharing my experiance and advising to be cautious.

Hey Romulus1 and SilvernightZ I want to share with you guys a problem that I am having with my Injen CAI.NO question it looks nice and drives faster but I would like to share with you. I washed my car and one time when I started the engine it was shaking and misfiring and it won't Rev up. I tried to drive it and it was going on and off on the road. I knew right away it was the CAI. Then last night it was raining here in sunny California and I was unfortunately caught driving my Z which I usually don't drive when it rains cause I have another car. Anyway I parked it last night in my driveway and today this evening I started the Z to move it inside my garage and it was shaking again and engine keeps dying. All the lights on the instrument panel came on . I tried to let it run for a few minutes and Rev it slowly and it won't rev above 3K. Then I tried driving it and it was the same as before it was going on and off and died on the road. I restarted it and finallly it is running again but I have the Service Engine Soon light now that won't turn off. I am so disappointed because how can a car not be driven in the rain or even on a car wash it gets affected! Now I have to go to Nissan so they can reset my service engine soon and then I am planning to switch back to the OEM air filters. it is just not worth the headache. Does anyone have this issue? Please share before I remove this intake and switch back to the OEM. Thanks

Yes, you have to remove the front bumper to install/clean the filter.

Have you had a Nissan tech, or someone else (autozone) check for a thrown code? If it's bogging down as bad as you say, a thrown code might help you see what the real culprit is before jumping on the CAI...

Just do the ecu reset yourself

shadoquad · 05-06-2013, 11:14 PM

I had the Injens in my Z. I really liked them. I noticed the moisture lag issue went away if I cleaned my filters. It does mean taking off the bumper, but that's not really hard to do.

joeyz10 · 05-06-2013, 11:59 PM

I just read another Thread about the same problem form goez's thread and looks like we have the same issues and he figured the filter injen is using gets wet from the water that drips form the hood. he performed a few tests and was able to duplicate the issue everytime. So it's not any bad codes, it's the CAI.

joeyz10 · 05-06-2013, 11:59 PM

Mine will come off asap when I have time. I have enough of this Injen CAI guys

Sh0velMan · 05-07-2013, 07:25 AM

I still can't fathom how enough water gets inside the area where the filter is housed to cause issues. The Nismo intakes I have put the filter in the exact same location, I've never once had water issues, even when I ditched the plastic pieces that keep water and whatnot from flying directly in to the filter from the radiator opening. I even had freakin scoops funneling air (and water and whatever else) from the radiator opening to the filters and never had any issues, even while driving in anger in the rain.

Maybe stop spraying your filters with high-pressure water?

If you're getting down in there enough to get the filter wet enough to cause issues, you're gonna be getting water on just about any CAI you could buy, so you should probably think about the K&N or JWT intakes and save yourself the trouble.

I've sprayed directly into the air damn with no issue as well as driven in a few really bad storms (raining sideways style storms) never had an issue. Maybe its cuz i have the "splash shield's" but what ever. I guess some people have issues

You're talking a lot of water needs to get in there to cause an issue. A LOT

joeyz10 · 05-09-2013, 10:43 PM

I am still confused cause today I took the car for a car wash and it was fine with no issues at all. I asked the guy though to spray the filter with that compressed air they use to dry the car doors....

mantella87 · 05-11-2013, 01:06 AM

I've had my Injen CAI through many car washes and a couple rain storms. Absolutely no issues. I chose Injen over Stillen because relocating a windshield washer reservoir is not permanent, cutting into the car however... sounds retarded.

It's not retarded so long as you do it properly. And it's in a spot you never see... So it's not visually a problem either.
