What aftermarket intake is good for '95 Maxima?
I'm looking to get an Injen cold air intake for my car. What other brand are considerable besides Injen?, and how easy is it to install the CAI? Does aftermarket intake really makes a big difference on power, fuel efficiency, and feel?

you're kidding right? Have you searched at all? Googled anything? Looked through anything? I can't even count how many times I've written this post. It's been answered so many time. Injen is not a CAI. It's a HAI. The filter sits right next to the radiator. A real CAI goes into the fender wall for real cold air. HAI give high end power and take low end. CAI give low end and take high end. Fuel economy really isn't effected by intakes I believe. Feel? what do you mean? All aftermarket intakes give and take but produce more sound basically. Point is make the choice of what you want.

+1 Place racing. Do some research on the topic. Also research your mass air flow sensor voltage.

One could custom make an intake, purchase a Ebay special that mounts in the fenderwell
or purchase used.

dude, the whole purpose of gettting an intake in general is to eliminate or reduce the amount of drag, friction, and restriction of the air. thats why all the intake walls are round and smooth. buy one from ebay. i wouldnt waste your money on a name brand one because after all its just tubing. i mean people argue that its the type of metal they use to keep the air temp down but really...? com'mon.
and i dont know how
you are but....

the point of any intake is to increase air velocity while maintaining safe filtration. more correctly to reduce impedence in the pathway of said air. the stock intake is designed to provide a balance of power, economy and noise dampening. any aftermarket intake will compromise somewhere. a HAI will reduce lowend power, CAI will reduce highend power, hybrid is a good balance but still suffers from some lowend losses. the increases can be fairly easily attributed to the phenomenon behind them. an engine will consume a fairly precise amount of air, measured in liters. a liter is a measure of volume, not a measure of how much oxidation potential said air has. a liter of hot air can not oxidize as much fuel as a liter of cold air, since the cold air is denser and contains more oxygen. with a HAI you lose lowend power because the filter is near the hot, hot engine in a cramped engine bay. because the incoming air charge is hot, the air is less dense, can oxidize less fuel for combustion and makes less power. CAI can pull a cold intake charge of air at low speeds, but since it sits in the wheel well, at high speeds there is thinner air to be scavanged from between the wheel and the top of the wheelwell. hybrid has a bit better lowend than HAI but is still in a hot engine bay, albeit a bit further away from the engine. this is also dependant on where the filter is placed. injen is behind the radiator and frankencar is in front/to the side of the driver's side wheelwell.
regardless of what intake you get, you will never gain a whole lot of horsepower unless the orignal design from the factory is absolutely awful or unless you have a whole lot of other mods in conjunction. by simple mechanics, an internal combustion engine uses MASSIVE amounts of air during normal operation. it burns an AIR/FUEL mixture. that's mostly AIR. because of the vacuum produced in a cylinder on the downstroke, air is VIOLENTLY sucked in through the just-opened intake port. with the kind of power behind air expanding to fill a partial vacuum and the necessity of air to an internal combustion engine, it's difficult to seriously impede the progress of the intake stream unless you really try. this is the reason that ram-air setups are complete BS. in order to ram more air into the intake by force you would have to go so fast that the drag produced by the intake scoops would far outweigh any "ram-air" benefits. a product of an engine's operation and also a necessity of it, is to suck in a lot of air. in and of itself it already is more than powerful enough to get that air from whatever the intake is connected to.
if you are going to cheap out on an intake, be careful what you buy. there are plenty of cheap foam filters out there. sucking foam into your throttlebody won't do you any good. a K&N cone will set you back $40 at autozone. all you will need to make a HAI with that is an adapter plate. alternately you can just make something yourself.
all that said, i love my frankencar hybrid intake. it may not make as much lowend power as a CAI or maybe even the stock intake, but for me a big part of my affection for a car is the noise it makes. and what a noise a VQ with a good intake makes indeed...

ok thank you DKO for that intriguing summary of how an intake works.

Seriously though I went to pepboys and bought a spectra cone filter for $20 and a budget ypipe and knocked 9 tenths off my quarter mile time. You should try it. It may not look good but its functional.
OH NOES!!! Where can I buy?

short learning time. i like to call it "crunch ILT" or crunch intense learning touchdowns!, the whole point of ITB's are to be independent throttle bodies so in the end we will have 6 mini throttle bodies. you know what they say!
