Drivetrain Ultimately best intake?

Stock is going to be the best engineered part for your car. Period.
You can really go with any of the aftermarket intake systems, because they all do about the same thing, make more noise. Intakes don't make power on cars with MAF sensors, and some even hurt low end torque. If you were to add an intake to a car that required the added flow (ie big turbo build) there would be a gain, but even the guys with larger turbos are still able to run a stock airbox due to the fact that they flow just fine.
No matter how much surface area you open up for the filtered air it still has to pass through an opening of about 1.5" at the compressor inlet.

Yes on the Turbo MINIs the intakes just don't make the power the companies claim that make them. If you just want one for sound then go cheap with our DDM street intake

If you are looking for power a Forge intercooler would be the right investment as it cools the air after the turbo.

Otherwise you can just put a high flow filter in the stock air box and be done. We only use the dry filters as we don't want to put oil through the MAF

I agree with the other posts about power,. You wont make much power with any aftermarket intake system, however some of the systems will allow you to drop your intake temps. I personally have a DOS intake which is no longer produced but my intake temps dropped about 15 degrees when I replaced the stock box. So for reference. If it was 80 degrees and sunny with the stock air box sitting parked the vehicle intake temp would climb to about 105-110 under the hood, and with the aftermarket intake my temps while parked would be around 90-95 degrees. I see the same difference while im under acceleration. The intake temp would be 10-15 degrees above ambient temp with the stock box and with the aftermarket intake the temp would be the ambient temp. So all in all not a huge difference but something to think about.

When I bought my car I was set on getting a good functional intake. I was set on the AEM ram air one. Then came to my senses. I don't really need that. It's still an intake and not really going to do very much but make more noise. Which I will admit was something I wanted. The stock JCW intake is great but I still opted for an intake. The non ram air style are all the same so there was no need to pay these outrageous prices for a tube bracket and filter. I was able to get the DDMWORKS one for a great price. The really hot engine bay temps worried me but I have not had any issues. Today was about 95 degrees in LA and I had no issues. I did open the hood scoop too.
If you don't like it its only a 10 minute install and they resell pretty quick on here.

I removed the blanket to allow more air pass thru. The K&N retains most of the stock airbox benefits including heatshield but allows for more fresh air to hit the filter.
On track days I'll take all the cooling I can get.

But, to get back to my main point, the AEM is IMO the best aftermarket intake available for the N14/N18. I just wish there was a way to have a similar system on my F56. I had to settle for an ARMA Speed unit.

Interesting statement and analysis.
The standard system runs a cold air pipe from the front of the car to the airbox which is all sealed and then feeds the turbo. Hard to see why you would get better inlet temps with another piece of kit.
All the air arrives in the standard box from outside the engine bay and the surface area of the pipework, assuming it is hotter for some reason on the standard system, isn't enough to transfer heat.
Either way, you have your data, I just can't work out why it would show what you saw.
For reference, all we did was machine back the compressor inlet mouth, replace it with a 2.5" straight pipe of alloy, fed from a 2.5" silicone pipe that leads to the standard airbox.. which is still feed from the front of the car. Works for 255 bhp at the wheels currently.

using a short ram silicone piece from forge, stuffs the filter right behind the opening in the grill that went to the stock box. sound is way up, feels a lot stronger mid-top rpm range especially after shifts getting back into it. stock felt a little stronger right off the line.
for temps, even with the stock system, my ambients would be high just sitting in traffic anyway i really dont notice it climbing any more than before.
without the tune it throws a maf code, could be contributed to larger turbo though also
