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

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 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.
