One of the first things that comes to mind when talking about modifying a car is: Intake, Headers, and Exhaust. So lets explore Intakes first...
Intake
There are basicly two different types of intakes on the market. "Short Ram" and "Cold Air" intakes.
A "Short Ram" intake is a filter on the end of the intake tube that sits inside the engine bay. Generally a shorter distance from the filter into the throttle body.
A "Cold Air" intake locates the air filter outside of the engine bay. It gets its name "Cold Air" from pulling in air from out side of the engine bay not the warm air from inside of the engine bay. Cold Airs do not magically cool off the air, it just brings in cooler air from outside the engine room.
Intakes that fall under the "Short Ram" catagory are: Jim Wolf Technology (JWT) Pop Charger, K&N Typhoon and Fujita intakes.
Intakes that fall under the "Cold Air Intake" catagory are: NISMO, AEM and INJEN.
There are some more intakes then these, but these are the main ones to look for.
The Performance Difference
All of these intakes will give you some kind of gain when installed properly. They all give you a larger more roaring sound from the engine bay at full throttle once above around 4000RPM. With a Short Ram Intake, there is less distance for air to travel from filter to throttle body. This makes for better throttle response and greater power at higher RPM's. Cold Airs do not have as quick of a throttle response but gain a little more in the mid range of the RPM band.
Air is constantly moving through the engine bay while the car is in motion. Filter placement is key here. Where the Short Rams place the filter is in a pressurized zone where air is directed towards the filter. On a Dyno, the car sits still so generally these numbers are lower, but in motion, this is where these intakes shine.
Filter placement is something to look for on cold air intakes. The INJEN intake places its filter infront of the radiator. At highway speeds, a cushin of air is formed around the filter directing on coming air around the filter. It is harder for the engine to draw in air when the filter is in a high turblent area like this. On the NISMO / AEM intake the filter is placed infront of the wheel. In this area air is less turbulent so the engine can draw in air with less effort.
With a Cold Air Intake you can possibly suck water up into your engine. To avoid this, look for an intake that includes or has an option to add a water diverter valve. This keeps water from being sucked into the engine by bringing air in through the valve rather then the soaking wet filter. The NISMO intake includes this. It is an option with the AEM. Short Ram intakes do not have this problem.
Is it possible for an aftermarket intake to void your warranty? Yes. Only if the Mass Air Flow sensor is damaged. The only time this happens is during instalation or if an over oiled filter is installed. If oil or any particle comes in contact with the MAF it could damage it. A MAF can be damaged with the stock intake as well.
The intake that makes the best horsepower gain for the money, sound, and performance that I would recomend is the JWT Pop Charger. $120 plus shipping and a independantly proven consitant 6.5 Horse power to the wheels gain. This is the way to go.

Re: found this on ebay, on intake's thought i would share (rmezz13)
I hope its a copy paste bc you left some stuff out. And the Newest CAI have a easy to remove lower section so you can pop the extra length off and re-attach the filter further up in the engine bay to prevent water and sh1te from getting into your intake, the main problem with CAI's. The one thing I think you nailed is that the pop charger is a very popular intake for the 350's and it is a good buy for a decent price.

I just wanted to throw my 2 cents in to what R350Zz33 posted.
-=Aftermarket Intake System Choices=-
When purchasing an aftermarket intake for your car you have two basic choices in style. Both can improve performance as well as enhance the look of your engine bay.
A "Short Ram" intake is a filter on the end of the intake tube that sits inside the engine bay, similar to how the stock air box functions. It is generally a shorter distance from the filter to the throttle body than the stock air intake as well as possessing a much larger air filter element with much less restriction of air flow than the stock assembly. They range in price from $45 for the E-bay versions of the more popular designs to just under $500 for high quality, name brand performance intakes.
Intakes that fall under the "Short Ram" category are: Jim Wolf Technology (JWT) Pop Charger, K&N Typhoon, GReddy Airinx, HKS Mega-flo and Fujita intakes.
A "Cold Air" intake gets its name from pulling in air from out side of the engine bay as opposed to the warm air from inside of the bay. Cold Air intakes usually get air from either the wheel wells or other spaces near the front of the car, but still take in air much cooler the high temperatures found inside the engine bay itself. Like the short ram intakes they will usually have a larger air filter element that takes air in with much less restriction in flow than the stock air intake.
Intakes that fall under the "Cold Air Intake" category are: NISMO, AEM and INJEN. There are many more brands then just these, but the ones listed are the most common high quality intake systems that can be easily found.
-=The Performance Difference=-
All of these intakes will give you some kind of horsepower and torque gain when installed properly. They all give you a larger more roaring sound from the engine bay at full throttle once above around 4000RPM. With a Short Ram Intake, there is less distance for air to travel from filter to throttle body. This makes for better throttle response and greater power at higher RPM's. Cold Airs do not have as quick of a throttle response but gain a little more in the mid range of the RPM band. Air is constantly moving through the engine bay while the car is in motion. Filter placement is key here. Where the Short Rams place the filter is in a pressurized zone where air is directed towards the filter. On a Dyno, the car does not physically move so air is not forced into the bay as it would be in a real life driving situation. Generally this will cause lower numbers, but it is not an accurate reading of how your intake performs in actuality. Filter placement is also just as key with cold air intakes. The INJEN intake places its filter in front of the radiator. At highway speeds, a cushion of air is formed around the filter directing on coming air around the filter. It is harder for the engine to draw in air when the filter is located in a high turbulence area like this. On the NISMO / AEM intake the filter is placed in front of the wheel, inside the well. In this area air is less turbulent so the engine can draw in air with less effort.
With a Cold Air Intake there is always a chance that you may suck water up into your engine. To avoid this, look for an intake that includes or has an option to add a water diverter valve. This keeps water from being sucked into the engine by bringing air in through the valve rather then the soaking wet filter. The NISMO intake includes this. Another option is presented in some cold air intake systems that include a “break away” section of the intake piping near the bend that takes the intake to the wheel well/outside of the engine bay. When driving in rainy/wet/soggy conditions the driver need only pop the hood, then remove the section of intake from the wheel well and remove the air filter placing it on the newer shorter section of intake. This is essentially a 2 in 1 (CAI and short ram) intake system and can be very handy if you live in a area with frequent inclement weather.
-=Factory warranty and your Aftermarket Intake=-
Is it possible for an aftermarket intake to void your warranty? Yes, as damage can occur to the Mass Airflow Sensor (MAF) both during installation and through over oiling of the air filter itself. If oil or any particle comes in contact with the MAF (such as oil from the filter traveling back through the intake towards the throttle body) it could damage it. While you can safely use an oiled filter with a MAF, it can be difficult to maintain properly and the main advantage of oiled filters is the ability to re-use them repeatedly. So do the math for yourself, the cost of repeated buying air filters, or the cost of replacing your MAF sensor to decide which option is better for you.The intake that makes the best horsepower gain for the money, sound, and performance that I would recommend is the JWT Pop Charger. $120 plus shipping and a independently proven consistent 6.5 Horse power gain to the wheels. This is the way to go for the budget minded 350z consumer looking for some show and go.
Hooray for lazy saturdays in the garage huh?

Re: found this on ebay, on intake's thought i would share (BigMACKenzie)
pro's and con's with short ram vs. CAI vs. popcharger? By the way, the popcharger isn't sold as a short ram system. It is sold as a filter charger with a heat shield (optional). It uses your existing Z/G tube.
