Hey everyone,

Got the Injen intake installed in my 2001 Maxima, and I noticed a few things that I wanted to make sure were normal,

1) when I start up the car, it sounds like there's a loud wooshing of air going on...the sound lasts for about 30 seconds or so before dying down.

2) when I'm driving, there's a very faint hissing noise that I sometimes here, is that normal?

3) for the plug that goes on the maf, I had to pull the wires out of the plastic sheath thing to get it to reach, should I wrap the wires in electrical tape or anything or will they be ok just kinda out there.

4) just reliability wise, I make lots of long trips, my drive home from school is 250 miles, is it ok to run the car for that long with the Injen? will there be any problems? And also, I know it's been beaten to death, but anybody have any problems with car washes, rain, etc?

Sorry for the long post guys...this is my first Engine mod (K & N doesn't count )

 

I have a Injen CAI on my 2K1. The wooshing sound in normal.
Actually kinf of nice I think. I do hear a slight hissing
sound occasionally also, but have no clue what it is.
As for the maf wires, mine reached, but I would tape them up
if I were you just to be safe. Driving long distances shouldnt
hurt it. If you have the CAI, DONT hit puddles of water going
fast. The water could splash up and into the filter. You should
have a plastic guard down there, but go slow thru water anyways.

 

The hissing noise is the throttle plate inside the intake track when it is not fully open, but not all the way closed. The noise you hear when you start the car is normal, and also happens when you turn off the car. Its almost like the engines last breath.

 

I have had my INJEN on for about 4K miles. In answer to your questions: just sit back and enjoy it, now that you have it on your ride....it's all normal and good.

 

1. large wooshing of air is just the engine sucking up air to crank over, no problems there. I noticed my car is always a little louder upon start then when warmed up

2. hissing is normal, but it should go away somewhat (or maybe i'm just used to it)

3. my plug fits fine. I just rotated the maf until the plug could fit on with some slack (check my webpage for pics)

4. reliablity is fine as I drive long trips between school and home. I just drove through a 1 hour rain storm here in California where I had my wipers at the fastest setting and I couldn't see anything. No hydro locking or such worries. There is a splash guard right underneath the filter, so as long as your not submerged in water you'll be fine.

good luck, have fun... expect to be filling up at the gas station as the car is that much more fun to pound on from light to light

 

Man you guys are fast! Thanks a bunch...looks like I'm going to sit back and enjoy the ride. I love this intake, quiet when I want it to be, loud when I don't, and worth every penny

 

Everything posted above sounds exactly right. Injen makes a good quality intake, so just drive it and enjoy the high-end growl. Just one question though, I find my Injen to be alittle quiet, is there any filter out there to make it louder than the way it comes stock??

 

step a little harder on the gas

my only problem isn't with the intake, it's with Nissan's stance on mods. I called the place near my house where I bring it for warranty work and he made a statement that leads me to believe he'll void my whole warranty for an aftermarket intake (I asked "would an aftermarket intake void my exhaust warranty?" and he said "well, if something goes wrong with the catalytic converter it will be traced back to the intake, yes.")

so I'm a little ****ed I have to swap my stock intake when I bring it in, but that's not injen's problem, it's Nissan's (and mine )

 

I have always taken my car in with all the mods still on, including the removal of my main cat. I even had them do my transverse link recall with my B&G springs on. They don't really care if its not causing any problems that they have to deal with. It sounds like your dealership is pretty picky. By the way, they can't void the warranty on anything just because you have aftermarket products on, unless they can prove that it caused the problem.

 

is it pretty pointless to get an intake on an auto? or is it still worth it? i have an auto (those damn 6spds have been so hard to find).. and so far i've only done aesthetic mods. my first performance mod would be an intake too, but i dont know if it would be just as good with an auto as a manual. sorry for whoring ur thread

 

this is from the K&N filter..

 

I know "legally" he has to prove the connection but in reality all he has to do is say "the intake caused the problem" and then I have to be ready/willing/able to fight him on it.

IAnd, if he's willing to equate an aftermarket intake to a problem with a catalytic converter I'm guessing he'd go to any length to void a warranty or make me fight it out with them. I'd rather take the 1.5 hours to swap the stock intake in and out again. Seems to me, in the long run, that would take less time than a fight with Nissan.

 

I agree, it's usually easier to put it back to stock (if it's time-effective) to avoid issues. Your dealer's attitude makes all the difference. Mine sells Stillen parts, and is pretty laid back about the warranty stuff.

Does it really take 1.5 hours to install the Injen intake? Is it worth it?

 

Anyone else notice the whistling noise from their intake increases in the rain??? Mine does... I still have the beginning part (with all the sensors) attached, and it vents air directly onto the filter.. I'm going to try piping that air straight down to prevent the filter getting wet.. I'll try to judge with my **** whether or not performance changes as well...

 

I meant 45 min to take injen out and put in stock intake, then another 45 minutes to take stock back out and put injen back in, sorry for the confusion.

And it really only takes that long because I'm paranoid about damaging the MAF so I try to be really careful. It should take about 45 minutes to do the whole thing (~20 minutes for each 'swap').

I'm just running into this because I'm having warranty work done on the hood but I got the intake sooner than expected and wanted it in.... if I had waited until the dealer's work was done (like I should have) then there wouldn't have been a problem. It's worth it because the car doesn't go to the dealer that often.

 

it shouldn't take that long to take the injen off and the stock back on, especially if you've done it as many times as I've had. Takes me less than 30 minutes now and you learn to keep stuff together instead of the first time where you bolt off every single bolt to disassemble the whole stock intake housing

 

Ahhhh...."masta injen changa"

 

don't make me bring out my bad of names

i'll cancel you from the vegas trip
