Especially with the filters being placed in an area as far as I know gets no direct airflow...

Your thinking to much in the lines of a filtered ram air system. The Nismo is a cold Air System like the AEM and Injen.

The Stillen G3 is an excellent system but it's not for everyone and some feel better about actually having a Nismo product on there Nissan, believe it or not.

Not really, I'm thinking in terms of a normal intake. The AEM and Injen designs are inside the engine bay, meaning they'll get fed air from the stock intake ports...

The Nismo will be from the fender wells outside the engine bay, meaning no direct airflow...

I agree having a Nismo part would be better, and I would like this as well. Which is why I'm with this kit. It's more expensive than the stillens and afaIk not as good of a design. Now, once we get one on a dyno and road driving to see how well it actually performs, if it out performs Stillens well then we have a winner and I will gladly order one.

...Provided they drop the price to where it should be.

Their cold air systems aren't. They're filters and lower tubes are located in the fenderwells.

In the case of the intake. I trust the NISMO product first. But remember, the R-tune line is NOT covered by warranties of any kind. Just in case you guys are thinking any different.

Pretty sure the nismo system is just a rebranded AEM. AEM does this for many makes. Mazda 3 came with a "Mazdaspeed" intake that was actually an AEM system.

This looks more like an Injen design ripoff than the AEM design. The main differences being they don't constrict the MAF section like Injen, or use a silly trickery like AEM. So hopefully this is a best of both worlds design, with an extra $100 tacked on to call it Nismo.

This intake has already been a topic on this forum before. Most people bched about the foam filter half way up the intake tubes. Personally I dont car for long tube intake designs. The last half of the intake tubing going into the TB is going to get heat soaked anyways, and the "cold" air (or whatever ambient temp air; that is always changing from season to season) that is coming in does nothing but challenge your tune. I prefer to me on a more consistant basis.

So will a short tube.

So will a short tube. It won't really challenge a tune either. They're built in variables and parameters which the ECU is designed to automatically adjusts too. Colder air will make more horsepower/tq and the ECU will automatically adjust to those variables.

A short tube intake is constantly heat soaked by the engine compartment temperature. The temperature variations in a short tube vs. cold air system are substantial. The cold air system does exactly what it's designed to do and has been proven time and time again with plenty of empirical data to support it. To much intake heat, which is constant with a short tube system ='s lost of horsepower. The only way to effectively reduce the heat is to place a barrier between the heat source and the tube, vent it or mover the intake into a cooler element of air. Hot air rises, while colder more dense air is settles lower. So placing the intake lower out of a constant heat source, produces cooler denser intake temperatures. If your not convinced, here's a little test. Feel the engine compartment after it's been run at normal temperatures. Heat rises off the motor and you can feel it at a distance. Let it cool down and you won't feel any heat rising. Simple physics.

As the hot air rises, it's reflected by the hood back onto the engine producing more heat, hence heat soaked. It won't move lower and vent to the bottom of the engine. It will keep recycling itself maintaining a higher overall temperature. Anything directly under the hood will become heat soaked including the intake tubes and the filters, because air around it is heat saturated. The mix of hot air from the engine compartment and cooler outside air will effectually cause a miniature vortex, causing a rush of trapped hot air being pulled into the intake. The stock engine intake area and the CFM it produces is not sufficient to reduce intake temperatures by itself. Lowering the intake and isolating it from the heat soaked engine compartment, does effectively lower intake temperature overall and at the same time increase the CFM. Sure there will be some heat transfer on the upper tube from the engine but not nearly as severe.

Do this little test; Let a water hose set out in the hot sun for a couple of hours. The outside of the hose will be almost to hot to touch. Now turn the water on and let the water run through it for a couple of minutes. The water inside the hose will cool the hose. This illustrates the colder air traveling from the outside into the intake from a constant source of colder air, thus dramatically reducing the overall intake temperature.

Sorry no, a short tube intake will not provide a more constant source of cooler air, like a specifically designed Cold Air System. At least Not unless you vent the hood and allow the trapped hot air out.

But is a permissible modification by Nissan. So when you roll into your nearest Nissan dealer you won't get a bunch of crap about running a aftermarket intake.

I'm happy with my z1 smooth tubes and cosworth filters. 370z already pulls air from outside the engine bay.

+1 (K&N filter though)
