Can anyone give me reasons why I shouldn't get an Ingen CAI for my 2K2SE Auto?
I know there are a lot of choices out there and half the threads on 5th gen are about intakes. I've decided against the K&N (at least until my MAF dies and gets replaced). I don't want to cut any holes but think I'll get the most HP and reasonable sound (I understand FC is a bit louder) with the Ingen - and the polished is very nice.
Don't know much about the filter that comes with it and if there is a water intake danger.

How about you Ingen owners - would you do it again? Did you change filters?

I've been thinking about one for my 4th gen cause i don't want to drill a hole either, plus, i live in Canada, so with this ****ty weather, it would be a pain to clean a CAI in the winter... These are the best prices i've seen by far on the new INJEN's... BTW, these are the highest quality filter systems made for the Maxima by far... Hope this helps... Power gains SHOULD be between a cone intake(more) and a CAI(less)

 

Yeah I saw that for $211. Nice price! I had heard some negative things about foam filters and thought that was what came with the Ingen.
I'm curious how quick the de-installation can be if the MAF goes and it's time for the "2K2 replacement".

 

It sounded perfect to me until I heard that removal of the front bumper was neccessary to access it everytime it needed to be cleaned.

CAI w/out cutting, zero maint. finish, great gains, etc, etc...
Whats not to like. Damn.

 

I don't know about the bumper thing... for the Ingen? Seems to me it would be easier to undo 2 mount bolts and one o-ring and lift the bottom tube assembly to pull the filter. Plus, I thought those filters were maintainence-free.

Uh.. I guess I didn't follow this.
Did you get a PR or something and wish you got an Ingen?

 

Roger that, Shadyz. But you lost me on the filter. Is there any such thing as a maintenance-free filter? Wouldn't such a filter have to be self-cleaning in order to be maintenance-free?

 

Absolutely. Why remove the bumper when the entire intake could be removed in ten minutes or less? Even then, it is only every 50K miles and that's really not a big hassle.

 

Well you've got me again. We've now moved from maintenance-free service to maintenance intervals of 50K miles. I'm unaware of any air filter that's rated for 50K mile service intervals. Is that what Injen claims?

 

f
Well, that's the interval which K&N recommends you clean and re-oil its filters. I wasn't aware of any filter which is 100% maintenance-free.

 

Hey Shaydz, if you get the Injen would you do us a favor and record the intake temperature before installation and then after. I'd like to know if the radiator fan
blows hot air on the filter at idle or if you'd actually see lower temps than the stock intake.

I'd need to rig an outside temp guage (with a wire) somewhere inside near the TB. Not sure how to accomplish that, but if it's possible , I will. I'd like to check 4 readings actually - before and after install.
- Idle - engine cold (just started)
- Idle to 2K RPM - no movement - engine warm (like before launch with no air movement)
- Running at +70 mph - warm ambient (outside) temp
- Running at +70 mpg - cold ambient temp

I'm thinking the results would be really interesting to see what part of CAI is really CAI. Also is there a Ram effect (which you don't get with a PR) that could cool down the air as well.


I'm leaning hard towards the Ingen and I thought the ApexI was considered maintnance free (maybe I was just brain-farting).

 

i thought that only the 3.5 altimas need to remove the bumper to install the intake.

 

You're right. K&N does specify 50K to 100K mile service intervals. I wonder though. Does anybody actually follow that schedule? My guess is that most people clean their K&N filters around 25K to 30K miles. Hmmmmm. Let's run a poll and find out.

 

Somebody on this board said the Altima's and the Max needed to have the bumper removed. I thought it was credible since they had or had installed one- can't recall. This would make the first time I heard that it was maint free. What type of filter wouldn't need maint? I only heard the finish was maint free. As in it didn't need to be polished to be kept looking good. I did research on this and stopped when I found the bumper thing out. If it's not like that, I'll buy one!

 

OK,
Here is a link to a zip file that has installation instructions.
http://www.vqpower.com/tmp/Injen.zip
It was posted by "gtr_rider"

THERE IS NO MENTION OF PULLING A BUMPER APART.

So "It's not like that", let's all buy one.

I believe I am.

That is how these unsubstatiated rumours get perpetuated.
The damn search. It seems that wrong information keeps popping up over and over. I've pulled wrong things from a long time back that have been put to rest in later threads. But I didn't see those.
I've started to get real diligent on the use of the search as of late.

Special thanks to gtr_rider for this. Hope this repost of the file link helps clear some stuff up.

For anyone interested in purchasing a true CAI, the Injen is the ONLY way to go! If it weren't for the high number of MAF sensor failures we've been experiencing, I might be willing to get behind the PRCAI and the Cattman CAI. But the possibility of having to lay out $600.00 to replace the MAF because you can't explain away a 3.5" hole in your fender is simply unacceptable . . . or at least it would be to me. But then I'm not in the market for a true CAI . . .

 

I agree. I'll still keep my stock box in the trunk though. I've got a 7/01 prod date and the original MAF. Just waiting for the day....

 

I agree with you y2kse its not worth it because you have to cut a hole in your body. Yup Injen is the only way. I would get it if I didn't have an intake already.

 

The only thing that concerns me is when I do need to bring it in, I'll need to switch out every time regardless of reason. It's not like they'll "not notice". The polished is rather an eye-catching piece under the hood. I'd hate for some technician notice it and wonder where it wnet a month later when the MAF goes or whatever.

Maybe I should take the "Take your Service writer to lunch" course.:

 

Incredible, Shaydz. You are the first person besides me to suggest that taking your Service Writer to lunch might not be such a bad idea. Congratulations.

Yes, of course you'll have to swap your stock airbox back in before you take your car to your dealership for service under a SES. Ain't no way you'll get them to cover a blown MAF with an Injen CAI installed. Even given the relationship I've got with my Service Writer, I wouldn't try that one. And of course, the objective is NOT to bring your car to your dealer for any type of service other than warranty repairs. That way they won't have a chance to see what you've got under the hood and write nasty notes in your service record.

 

The guy I usually get is real new though. 6 mos. He did order the parts last Fri for the TSB on the vibrating hood at "highway speeds".
It does vibrate, but I've got to get it up to 78 - 80 (My interstate speed) to make it happen. He didn't want to order parts till he rode.
I explained to him the dilemma of no 70 mph roads around and he was pretty cool. He just took my word and ordered them. Would like a writer that's worked there for 3+years, has his own tricked max and scoots down to rockingham once a month. Hell, I'd bring the beer.
But until, I'll have to srip the mods for warranty stuff.

And I bought the 100,000 mile. This is going to get old...

Gotta get some shut eye.

Shaydz

 

The only reason I dont buy the Injeen, is because I love my Frankencar. Very simple reason. When someone Dynos both and proves a difference to me, then I will consider it. The Injen is an awesome intake though. When it gets certified as 50 state legal, i might lean more to it. I had a friend who got impounded over the weekend for an intake and exhaust...some cop on a mission.....He was speeding when stopped.

 

Roger that! The first 5th Gen intake that gets C.A.R.B.-approved is definitely going to have a leg up on the competition. That's one of the reasons I bought a Berk Tuning intake. It didn't make much sense to spend a lot of money on an intake when I'm going to replace it with the first C.A.R.B.-approved intake that becomes available.

 

Did a little search. Found on a Saturn Motorsports site ( http://www.saturnsandiego.com/Motorsports/ )this statement.
Don't know if it is true for all Ingen intakes. Not sure if there is a way to look up specific Exemption ID's to see a description.

Doesn't really apply to me in NC, but thought you might be interested.

 

Thanks, Shaydz. Injen's CAIs for 5th Gen Maximas have been submitted for C.A.R.B. approval, but C.A.R.B. approval has NOT been issued yet. When that happens, the State of California will issue an E.O number. Until that E.O. number is issued, Injen CAIs will be just as illegal as every other aftermarket intake currently available for the 5th Gen Maxima.

 

Wow!

You've got a tough burg over there to mod in. You'd think it was enough to try to keep you foot off when a Civic is revving like a weed wacker next to you (and his is C.A.R.B. approved), but if you do have an intake (I saw the ARB list - didn't see anything above 1998 for Maximas) you have to worry about that.

We just have to look out for tractors...

i've had my injen installed for 3 weeks and my MAF died last friday driving home from work. i can't make an absolute correlation between the two but i'm pretty suspicious.

 

I pretty sure regardless of what intake you put on, the MAF would've conked. What is your production date. I read somewhere on .org (I hate doing this without citing the source) that there was a Nov cutoff when they started using a different MAF (the one you'll get on replacement). And no one has had a problem after replacement.
I know when I put the Ingen on - I'll give it a month tops. Wish I could just tell them to replace the damn thing.

Hope you changed out to your stock box before taking in for warranty service. IMHO, You'll be good after they replace it.

Shaydz

 

of course not i'm a total fool. in my ultimate stupidity i thought it was a fuel system problem and took it right to the dealer. the only upside to this is that the replacement has a "parts" warranty that exists regardless of modifications done to the car. and don't worry i have that one in writing.

 

So, after you get this MAF replaced, you can put your Injen back on, and not worry about switching out when you come in for other warranty work?

That would be great - almost a thumbing the nose at the tech that opens the hood and sees that beautiful shiny intake mod.

Still, unless I knew it was that "part", I'd still be leery to keeping it on when you go in. Glad it worked out for you.

Shaydz

 

i think you're missing how stupid i really am... i didn't take the injen off before it went to the dealer. now, since i have to buy the ****ing part it's got a "part replacement" warranty that's separate from the "factory" warranty.

 

Yeah my car was produced in Oct 2001 I think, and when I was installing FrankenCar intake I took a look at the MAF and it had some sensor inside of it.

I remember that somebody posted a while back a picture of two MAFs from 2002 Maxima. One had some sort of thin wire and other MAF had a some sort of covered wire and that is how my MAF looked inside.

Maybe they started using new type of MAF in Oct 2001.

Many discussions here were about oil from K&N filter damaging MAF, when people suggested engine fibration that could be the cause.
Nobody really knows what really causing MAF to get damaged.

 

:Shock:

Man, I am so sorry. That is a big chunk'o change. I don't think I'd like to trade the Part's warranty and $500+ for Factory Warranty and switch out when you come in.

I did not realize your situation. Thank goodness for the .org and these experienced posters out here that can give us heads up BEFORE the problems come out. Your heads up was 3 weeks late. Sorry dude.

We feel your pain...

 

it can't be oil because i'm using a monster filter. it's either vibration or the fact that they're just pieces of shvt. i tend to think the latter is the case.

 

thanks, now you fully understand.

 

I took my car into the dealership with my frankentake on. They didnt say anything. They said they have to prove it caused the malfuntion. The service manager said that they would love to help me setup a SC or something later on if I wanted to. Of course that will void the warantee but it was cool that they would like to help.

I have had no issues with the MAF yet, but I will have to bite the bullet on that one if I have to pay, becuase they have already seen the mod. They are pretty cool about this stuff though. They better be after they wrecked my car.

BTW - I am looking at moving over to the Injen soon. It is just way too hot under my hood in the sultry VA heat.

 

i'm in nova too, in fairfax. aside from the maf problem the injen is wonderful, it blows away the berk (which i had prior). it doesn't matter that they've already seen your intake, if the maf dies swap out the intake and take it in. they can't prove that you had the intake on when it died. all they get is a code and nothing more. it's not like it says "owner was using intake X when maf died".

 

LOL

 

Yeah, I am not worried about it at this point. It hasnt blroke yet and I have run the crapp out of this car before. A few times I have shifted @7000 rpm. The MAF should have broke by now. Between Hot, Cold, or rough it is doing OK.

 

we have seen a blown MAF already with injen installed.....that's one of the reason that I would say no on injen.....dont get me wrong, maybe its not injen's design. maybe it's our car too weak to handle aftermarket intake...who knows.
