what is the best intake short ram or cold air

jpit

Here is a quote from Mike Kojima (perhaps the most well-known Nissan tuner) when he tested the G3 on a 370Z automatic

"Since the stock intake system is so efficient we were pretty sure that the Stillen intake was not going to make much difference and we were both right and seriously wrong. When running on the dyno, the Stillen intake produced on the average 3 more whp but less torque at 270 whp and 216 lb/ft with the power gains coming high in the powerband above 6700 rpm. Below 6700 rpm, the Stillen Intake lost a slight bit of power and torque. This isn’t the whole story though. For the sake of curiosity, we removed the front bumper fascia and ran the car with the airflow of the dyno’s cooling fan blowing straight on the filters. We were amazed to see that the Stillen intake belt out an additional 10 whp nearly completely across the board! Not believing our eyes, we ran the car with the bumper cover off for many pulls and the numbers repeated. We then replaced the bumper cover and the power numbers dropped to what they had been.

Stillen’s cold air intake is clearly a superior design with great power potential but the bumper traps hot air in the vicinity of the filters which nullifies most of the gains. We hope Stillen reads this and creates a bumper vent and heatshield kit so that the full potential of this great intake can be realized. Since people do not drive without a front bumper we are only going to show our with bumper cover power results."

Link to article? I have yet to read this yet or it is very old news.
The last time a shop post an install/review of the Stillen Gen III it was proven they changed the stock numbers because a week later their tune came out showing massive gains yet no one else got those gains.

I remember seeing this a couple of months ago too, it was kinda what made my decision not to get the G3s, atleast for the time being. So to me the important thing to do is do the Modshack DIY vent thing no matter what intake you have for full benefits.

On a side note, I still havent fix my front bumber scratches yet but when I do I will be doing the DIY, and will see how things go with just KN drop ins for now.
