Why is that?

Sure, you need more, less restrictive airflow into the intake, but most aftermarket intakes don't do a good job doing it.

Ideally, the BMW Performance or Euro Box provides the best gains, which are minimal at best

Gains by proper headers are just as much proven as gains by proper intake. I am not debating the level of gains. I am merely pointing out your statement of "complete irrellevance" being senseless.

A cold air intake that sits in a hot engine bay will do you no benefit if you have more volumetric flow

Correct! Which is also applicable to all platforms.

Yes there are differences but your statement on this being completely irrelevant just does not make sense.

Ehh, the CSL intake for the E46 M3 could get you up to 20hp, some people struggle getting that from a tune, intake, exhaust, etc. on the N51/52 platform.

Standard CSL intake doesn't make that much power, but the Evolve unit makes significantly more than that. Karbonius unit is in the middle.

off topic, but jesus those CSL/CSL rep intakes are expensive. £3250

Yup. Made at the same facility that makes the CF for some of the F1 teams.

No, AFE and more than likely DINAN provide the best gains - I tested the AFE vs the BMW intake and it made more power at every RPM.

Are you a speakin of the Dinan ram air intake?

sadly there's nothing to debate, increase airflow releases extra few ponies, nothing huge but it's there

The assumption is that the stock intake is restrictive. Hence all the aftermarket intakes.

Tusser wasn't a pastor, and what proof do you have that you are increasing air flow or that the engine needs it?

No, the assumption is that general populace is a bunch of lazy morons who think every car will benefit from a CAI and muffler instead of actually doing a bit of research.

You should just upgrade to this electric turbo filter. No increased drag on the engine and will force even more airflow into the engine:

yeah, I don't need to proof anything as you haven't provided proof to disproof the validity of all (most) intakes.
FWIW. Just dropping in a K&N filter increases the mileage on all my cars and sound better in the process.

Didn't Mythbusters do a show on CAIs? I believe their conclusion was they were a waste of money and only had minimal gains at best.

Correct. Even Companies who SLIGHTLY alter the inlet on a pre-existing factory air box, only produce slight gains.

Love the research you did!

That aFe box producing 5hp at the wheels seems like an excellent product to me. It is almost as good an investment as headers. Headers will get you somewhere around 15 to 20 hp at the wheels. But as headers cost 3 to 4 times as much (even more when you would add labour).... well..
