most CAI's are shit. seriously, you're removing something designed by a team of engineers for something 3 guys did in a fab shop. is it surprising that it doesn't give huge gains? why would bmw engineers leave HP on the table? Yeah maybe 1-2 to quiet it down but you really think most cars intakes are restrictive enough to gain 10hp? not likely.
NO stock car runs at 100% of its potential!!! Its all about fuel milage and engine life! This is why you can get 15-20Hp just from the ECU program. Most parts around the engine are very restrictive, stock air boxes and exaust for the most part. My 4.6L V8 truck came with stock single 2" exaust, what a joke, and the airbox opening was about 2.5"-3", with the rest of the intake and MAF at 5"...

There are cars that are built for fuel economy and others built for speed .. you cant tell me that the s2000 or m3 are not running close to there full potential. I heard stories of people putting mods on an s2000 with it only dropping in hp

how does restricting airflow to the engine improve fuel efficiency?

Im guessing less air volume less fuel needed. But you can argue more power (within reason) = better hp:weight = less fuel consumption.

Exactly this... lol... IAT's will match what the IC can cool basically.

Most CAI's will show gains not because of placement, but because of flow increases... if the factory setup isn't restrictive in the first place, gains will be minimal... If the aftermarket setup is worse (maybe not with flow capacity, but say with velocity and/or turbulence) you might loose power.

On NA cars, a CAI will show gains if the induction air is coming from a colder area then the engine bay of course.

Here is another video they did on a non boosted car .. just called it PODs in Australia i guess

tb controls airflow upstream of air filter. the more available the air (less restriction of airflow, less compression required to pull air) = more efficient.

that's pretty basic physics, unless i'm missing something.

Yeah... the classic hot air intake lol. The filter is sitting at the back of the motor and they are running with the hood closed on the dyno. No surprise that it made less power. The stock air box on that car is definitely superior to that set-up.

tb is controlled by ecu which takes air flow rate from mass airflow sensor

.. just adding on

Exactly the results I would have expected...

Hot air intake (cone filter) in the back of the engine bay vs. the stock airbox which is designed to pull cooler/fresher air.

Cooler air = denser = more power...

Another useless test from these guys

unless tests but funny how many people pop open there hood and I see the same type of hot air set-up.

If it makes the car sound louder... it must be faster right?

When I bought my intake, I knew there was gonna be minimal gains in HP.
I bought it more for the induction noise.

agreed... the only time it doesn't really matter as much would be on a turbo car... where you will probably see a flow increase and the IC will take care of bring the temps down anyway so you will generally see a gain if the stock airbox is somewhat restrictive.
