I don't know anything the current intakes out, i need a refresher.
edit: now that i read it again, i would just go with drop in k&n filter.

Isn't this in the stickies already??? 
BTW....I vote for hacked airbox, its not in your poll list.

1) The Frankencar Intake is just like the Stillen/JWT "POP"-style intakes except that the Frankencar/Berk intakes comes with a midpipe that replaces the OEM resonator that sits inbetween MAF sensor and throttle body. The Frankencar/Berk intakes have gotten the nickname "hybrid". A Stillen/JWT or any other POP setup can be converted to a hybrid by simply adding a midpipe. There is nothing remotely special about a Frankencar intake. Nothing.
2) A midpipe has yet to be documented to make any power gains, but it does introduce quite a bit more intake noise and a generally deeper sound. Most owners tend to like this induction noise under 1/2 to full throttle. The sound emmulates the sound of an Acura NSX.
3) The Injen intake is not a CAI. It pulls air from the drivers side front portion of the car just to the side of the raditor. IMO, this is probably the worst place to be drawing air. Also, the Injen piping is routed close to very hot engine components (manifold, head, block, tranny) which will heat soak the nice shiny intake piping.
4) The Cattman/Place Racing/Warpspeed CAIs are the only true CAIs on the market. These setups pull air from an area that is sealed off from the engine bay. These intakes pull in ambient air. These intake require cutting a 3.2" diameter hole near the battery to route the piping. Many owners are afraid to cut into their car for fear of resale problems. The truth is a good cut is not noticable because the hole sits in a location that is shielded by the battery and wiring harnesses.
5) The hacked airbox is when you cut out the lower airbox to bring in more air. This results in more sound, POP intake power, and the introduction of hot engine bay air.
6) The POP/hybrid/hacked airbox intakes are assumed to make better upper rpm power at the expense of lower rpm power. "Boggy" throttle response, especially in hot weather is common with these intakes. The lack of throttle response is most likely due to removing the pressurization effects of the stock intake tract and drawing in hot engine bay air.
7) The CAI intakes are assumed to make better lowend and mid rpm power. The CAI intakes don't seem to suffer from the "bogginess" problems because of the 14" longer intake tract which is able to store a column of air and in a sense keep the air pressurized, less turbulent, and cooler.
8) Dynos and track results have proven that all the intake setups POP/hybrid/Injen/CAI/hacked all perform basically the same assuming the air outside is cold and the engine is cooled off.
9) Hybrid/POP/hacked/Injen intakes pull in underhood air therefore in the summer these intakes can be drawing in air that's over 140 degrees. A CAI will be pulling in ambient air. It has been shown that the engine bay air cools down to near ambient once the car is moving at 30mph+ for a few minutes. The problem is the temp sensor and knock sensor typically will detect the extremely hot air coming in therefore from a stop the car's acceleration can feel weak in 1st gear. At the track this can cause a much slower 330' if the engine is not cooled.
10) In the end it comes down with what you're will to pay and what kind of driveability you want.

When i just had an intake install i just felt like it redline/shifted harder, It takes the laggyness out of it. im sure its not hella hp by its self but when added with other exhaust parts im sure it adds. It has to add hp, other wise why waste money on it!
A Minority Opinion For INGEN - from my VQPOWER comments last year.....
Yeah, I just decided to put an Ingen on my '99 GXE, even though some folks call them a "warm-air" intake. Well, it did install as advertised, but since I was still wondering about the "warm-air" label, I put a Radio Shack outside digital thermometer probe inside the main tube, through the valve cover scavenger hose. Guess what? Air temp in the Ingen went to over 122 degrees F with outside air of 74-78 degrees! Airplanes can't take off when the air is that hot!
So I stared at the engine compartment for a while, reversed the lower tube to drop the filter lower, then took off the driver-side lower splash-shield, and intake temp dropped into the 90s. Better. Then I covered the filter on the top with a plastic bowl, to keep the hot radiator air away from the filter. Now intake temp drops to 4-6 degrees above outside air temp! So, now it acts like a cold-air intake, and the car feels much more responsive....

The car has much better throttle response. Ingen now sells the filter covers to do the same thing... This works much better than a hacked airbox with a K&N filter that I tried first. Intake air temps were over 130 degrees on the dyno! Now intake is 5-10 degress over outside air temperatures.

I don't think any of that stuff matters. I have the Inken intake. But with a mass air flow sencor, it compensates for cold and warm air. It also does not let any more in than before. So i guess if you think about it it useless with our mass air flow sencor. But if you could eliminate or have and afterarket mass air flow sencor then it might work. BTW if you have a mas air flow sencor or know of a brand. Let me know i'm seaching.

i used the hybrid intake setup with my warpspeed y-pipe, i'm unsure of the exact gains but i can tell u that the two together produced alot of extra hp. i would go with a hybrid setup because it gives more power throughout the entire rpm range rather than just at the top or bottom as cai's and popchargers do

Place Racing with the drilled hole for the win. I got one and the next few days I will show you why. I put mine on and its a beast with great flow and the installation was perfect, I mean the CAI was enginneered so well to fit our cars.

i use a hybrid intake setup because it frightens small children when i drive through the neighborhood
it also has caused temporary hearing loss when a friend of mine was bashing my import (mustang owner
) so i had him listen to my intake by putting his head right over the filter nearly resting his head on it. then i revved it hard and he had nothing to say about my vq after that.
about the intake debates though- they're really nearly pointless. i mean only a few hp seperates one type over the others; such an insignificant amount that you couldnt feel the difference.

I have an Injen intake and Ive been reading that stock is better.. but I honestly
felt a differance after install. I love it. Oh yeah Ive beaten a 4th Max with
a place racing CAI... Bairly by my back door, but I beat him 3 times.

Zack already proved the crappiness of a midpipe on a 4g ... Feeling and seeing #'s are different things. This b!txh as.s thread is almost over a year old. Zack, POP is my chioce, proven gains and no funky curve, at the expense of a little low end.

I believe for most modern cars, it is hard to improve upon stock intakes, unless there isn't a concern with a major increase in intake sound.
Design engineers that work for the big auto companies these days have access to massively powerful computer workstations for computational fluid dynamics modeling. These computers can be used to derive the best layout for an intake under a variety of engine loads, air flow, temperature, altitude, etc. The shapes of the intake parts may look highly convoluted, but there is generally a reason for the odd appearance.

If it sounds like you're going faster, your brain will think you're going faster even though you might actually be slower. Various intakes on the Maxima make a lot of noise and some vibration above 3500rpms. All of that can confuse the senses.

Anyways, altho it probly isnt anything to rant about, im sure a real CAI with the filter inside the fender has to provide SOME kind of gain, regardless of how much...it does do something....its common sense....

DO NOT BUY AN EBAY INTAKE!!!!! my friend johnny has an 89 accord, bought an injen style intake offa ebay for 50 bucks, and when we went to install it, we found that the bends in the piping were EXACTLY OPPOSITE of where they should have been! needless to say, we still cut the pipe to pieces and duct taped it together until we went to home depot to find some rubber hose connectors.
I have a 95 auto with an Injen. i chose to not get a PR style b/c i don't feel like cutting a hole in my fender and like Majik said "how much air can the PR CAI pull in when its tucked in by the fender." that was one of the first things that crossed my mind. The Injen intake sounds niiice, and i can honestly feel pretty noticeable gains at 35000+rpm. Injen also gives you free liscense plate frame and decals... These, if used correctly, can achieve gains of 30+ hp/torque!

wow the 2 posts above nmex are just stupid... it has been dyno proven that the stock midpipe produces the best hp. Also the injen design doesnt make any sense, ok lets put a CAI RIGHT NEXT THE ENGINE AND THE RADIATOR! so smart!

I bought and installed an Injen CAI. Been using it for 2 months now, and I love it. Makes a great sound, and I felt a HUGE power gain after install around 3500 RPM range. And Injen is dyno proven, which is another one of the reason I purchased it--I wouldn't hack at my car or start cutting at it if I wasn't positive it wasn't going to get some type of major benefit, so this way I felt more safe, since I do plan to sell it after I finish college in 2~ years,
got my Place Racing CAI for 65 bucks (what a deal), and since then im in love, sounds great under heavy acceleration lets say +3000rpm, and is way better than my old stillen popcharger, btw common sense has something to do in this situacion: popcharger = engine bay temp air, PR CAI = outside temp air (i guess is colder than under the hood)... but hey this is just my opinion
oh and other thing, some time ago when i had my auto max (99) stock i street race a friend who has a another auto max (96), i got him by 1/3 car length... some time after that we race again but we both with upgraded intakes: PR CAI (me) vs Injen "CAI" (friend) and this time i left him for about 1 car length, of course these are ghetto measurements, but at least true story
NOTE: both races started from 0 miles and ended about 80 mph

lol @ all the mixed opinions. i used to have a civic (go ahead and bash).....but anyway did a custom setup using an AEM V2 system and a little extra 3" aluminum piping from home depot and a K&N cone filter. i first installed the V2 as normal and took some measurements behind the front bumper. if anyone knows anything about the 92-95 civic front bumper, you will know of the black pieces that fill the gaps...well if you cut that out it leaves a big hole right in front of where the filter for the regular V2 intake would sit. well i did some cutting and a lot of measuring, etc. and ended up with the filter right against the hole in the front bumper pointing forward. yes i know it sounds afro-engineered, but it sounded amazing and i felt a fairly good gain in power out of it.
the point of this being, if there were a way to do this to my Maxima, i would most definately do it

If that is so, then why did my car run better with an HAI setup during cold weather days and ran like a dog during hot summer days? BTW, I don't have that crappy HAI setup anymore. Fact: cold air = denser air = better performance. Also, dyno graphs prove that whenever you add a power-adder to your car, it throws of the air/fuel ratio. So there goes the theory of the MAF compensating for things.

Wouldn't Injen and Cattman have realized this and done something? Help me make sense of it! I have an Injen and it feels like it really pulls after about 3300, so it must be doing somethin other than makin noise, right?
Man there are too many opinions on intakes. I heard if you get some exaust mods like y-pipe and cat-back the intake system doesn't lose low end due to a more free flow setup. I don't know I was thinking of a JWT popcharger put onto my stock mid-pipe. Would I lose much low end if I had the JWT with a y-pipe or catback?
