It's not a cold air intake... it's actually a warm air intake.

[Beancooker]

Injen, Berk, Frankencar, Popcharger, and GAB (Ghetto Air Box) are NOT "true CAIs"

Only the Place Racing/Cattman setup are "true CAIs"

The rest are "warm air intakes"

End of discussion.

Stop calling these "COLD air intakes." If it is anywhere in the engine bay, it is sucking warm air. Period.

[jltibbs]

ok, so can someone get this guy a drink?!? it's ok noah, i still call min injen tech a CAI. relax. we're soon to catch on.

[danielekfuj]

oops. BUT, since the filter on a "warm air intake" is still positioned over the bottom half of the stock air box, and cold air goes into the intake tube by the hood latch and down and back up into the lower portion of the air box, therefore, the intake is a cold air ram intake???

At least I can post this without worry that Noah "Chopping Block" Skelton will ban me...

[Beancooker]

Pfffft... I just get saddened, when people new to tuning think that a three foot long piece of tubing that is pulling hot air from behind the radiator, is a CAI. It's just as saddening, that some people think that an intake will add 20+ HP. Some companies actually market these lies. I have yet to see, or use the 20+ HP intake. This is just here to set the record straight!

The cold air intake will add a little more HP, because it is pulling in cold air. However, unless the air is coming from inside the fender, it's not a CAI. Most intakes marketed for the Maxima are actually warm (or Hot) air intakes. Pulling hot air in from the engine bay will not help your HP, persay. The stock intake is very restrictive, and just using 3" piping will let it breathe a little better. The HP difference between stock airbox and a CAI is about 5 HP. The difference between a stock airbox and a WAI is about 5HP. The largest HP bolt on part for our cars is a Y-pipe, which will get you about 16-20 HP at best.

noah FTW!

What's this TomFoolery?

Noah, call my CAI a WAI again and imma gonna haveta .............

Whatcha' gon do?

[homeslicej2]

The a**, the a** . That's why I don't worry about buying an intake, well that and I have the SOHC 2.4 so it's not worth the $ anyway. Although I did think that the CA extensions for the intakes were supposed to remedy this problem.

[scaramouche]

ok guys my question is: what's d difference between a CAI thats located in the fender and the one thats in the engine bay. and how huge is the difference?

[audtatious]

The fender should pull cooler air than simply under the hood. Depends on the car tho. For the VQ35 Maxima, running a tube intake increases low-end hp which is where we don't need it. A short-ram increases mid-high and probably does a better job. Having the intake mount to the fender will probably give more low-end that a short-ram and should be better than a Injen-style due to cooler air.

What does this really mean? probably a hp or two. Of course, you won't have heat-soak as soon and it will work a bit better in heated conditions.

[Fenvy]

I guess all of us turbo folks should run cold air intake.

By the way, anyone seen any dyno between true cai/short ram on the same car? Some argue that the gain is really nominal and I tend to lean toward this argument, that it isn't worth paying that much more for additional 1hp/1tq gain.

In any case, I would like to seen some dyno on this...

[audtatious]

I agree that, in general, there is a nominal increase. Hell, 1hp +/- is absolutely nothing.

[dandaman0139]

there is no real big difference, all i did was attatch a cone filter to the mass air flow sensor. what did i get maybe a 3 horsepower gain, but what really matters is that i get that extra roaring sound out of my engine. and if i had to pick paying 300 for a CAI which gives me a +5 HP or a cone that cost me 35 for a +3 hp gain, i would save those 265 dollars for something more useful, like maybe put it away for headers or something

[D_roc]

I kinda agree wit you man I used to have an CAI in my mercedes that i bougth from ebay and it sucked, and whats da point of spending lot of money on a couple of horses and if you want the loud noice god damit take the freakin mufler out don't people want a nice smooth and quiet ride

[audtatious]

The Injen is purdy tho

[dandaman0139]

without a doubt it is, but not pretty enuf for 300 dollars

[audtatious]

Two fifty if you shop around

[A.Tech]

I know, a lot of people don't get that. Anything that is really near the engine that is a short ram is a Warm air. I mean how in the hell you think it is gonna suck in cold air when the engine is like 1 foot away?

I love the my W.A.I though. I feel that it is just better in a lot of ways for response and looks cool when it is on, roaring as it shakes. I know CAIs roar too but I have always heard these roar louder and plus they are closer to you and I can hear mine all of the time just sucking air so loud.

[audtatious]

Warm air or not, if the factory intake is restrictive, adding a "WAI" can increase power based on having more airflow. On the VQ35, a GAB is dyno-tested to have more hp than a short-ram or "long ram" aftermarket intake.

Heat is only one consideration.

[Klepton]

I am new to tuning/modding and have a few questions regarding Air Intakes:

I found a CAI from Cosmo Racing that claims to give a performance gain of about 7HP for about $95. I also found they make a Short Ram Intake that gives about a 5HP gain for about $65. If I don't intend to race my car (either on track or street), which of these Air Intake systems is best-suited for me? Keep in mind that I don't currently have, nor plan on getting, a supercharger or turbo for this car. I have read about, and am afraid of, the potential engine-lock problem that can supposedly be caused by a CAI system sucking too much water from the fender well.

I simply want a slight increase in HP while doing my daily driving. Any recommendation(s) will be greatly appreciated...

Oh, I forgot to mention that my car is Automatic.

I have their short ram.... Don't expect to feel anymore power, but the thing sounds awesome. It also looks great I think. They don't provide any instructions, and the SRI doesn't sit behind your battery like their pictures show. It actually sits out front between the battery & the Rad. hose, so expect to do some inventive fitting with it if you chose to go with them......

[Klepton]

Being that I'm not a mechanic, and therefore will probably not install it myself, is there another SRI you would recommend that might be easier to install and/or a better fit?

[snwbrdr435]

i want to put an intake in my 00' I30 cant really find anything i like any oen have any suggestions?

[brianw]

Look for `00-`01 Maxima intakes, they'll fit your I30.

[Fenvy]

meh, I have seen you create similar thread when you first become a mod. Is there really a need to deliver your point across again and again? I'll call my Injen cold air all I want.

who cares

Look at when I created this thread. It was 5 months ago.

Second, if you spent any time at all in this forum, you would have understood that it was created out of humor towards a few other members (friends of mine) that call their WAI a CAI.

Third, if I want to deliver my point again and again, trust me, I will.

Personally, I would go with the Cattman, and if you don't want to spent that kind of $$$, go with the Frankencar. Those are the 2 best IMO.

[orgullo]

I've got a How-To that I did for an Injen intake. "How-To" turn your WAI Injen into a TRUE CAI. I also did a battery relocation write up at the same time.

Here is a link... I'll post it up here if you like.

Bolt on modifications are good for performance to a point. Getting into the nitty gritty of WAI and a real CAI is really not worth talking about or getting defensive about. As any mechanic will tell you that a vehicle's intake is designed to let the engine breath. It's also the engineer's way of tuning down the engine for emission laws. But not to get technical here. In all else, if people want to do some simple HP gains, intake and exhaust are a must together. All that air getting sucked in by your WAI or CAI has to get out just as fast if not faster than it coming in. But I'm sure the majority of the people on here are on a budget. LOL!!!

[hsckris]

will add 20+ HP. Some companies actually market these lies. I have yet to see, or use the 20+ HP intake.

i think it depends on the engine/application

look at this graph:http://www.f5air.com/feat_ma2817.html

if i'm not mistaken that was tested on a truck that is on this forum.

[Soravia]

Cut a whole on the frame under the stock box and attach an L shape tube with the opening facing the front of the car.

Now you have Cold RAM Air Intake. Change the filter to Hi-Flow Dirty Engine if you want more air.
