Intakes for my 03 ZHP...

Ehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh...it's a safe bet all things being equal our butt dynos wouldn't notice a thing relative to the cost outlay. My feeling with those intakes is there are other things maintenance wise to do that offer real benefit in performance or peace of mind categories. VANOS seals, DISA rebuild, to name a couple. GruppeM is exception because you actively hear the pleasurable induction noise and has benefit to autox/track situations (hearing it through helmet/wind) it's worthless all the same from a performance standpoint.

Well no arguing that but that's a different point and pretty subjective.

The simple fact is there are proven dyno numbers to back that most intake systems offer some kind of power gain.

Is it a bandage on a head wound if your vanos or disa's are failing causing power loss, absolutely. Anything else though is purely opinionated.

True, true.

Afe stage 2 (the one with the lid) best option for increased airflow.

If you revamp the stock one that's a nice one too. Just swapout the charge pipe for one without ripples in it.

That would be the stage 1. I'm not sure why they call it that when they claim larger gains on the stage 1 and it's priced higher.

i like my aFe intake purely for the noise aspect. it was worth the money i spent on it

Same, though my price point would be closer to the $250 and under, maybe ~$350 for the GruppeM

Don't buy an intake expecting performance benefits, buy it for the induction noise.

agreed. i was fortunate enough to pick up my aFe stage 1 used, for $250CAD.

Not true, airflow increase is needed for proper tuning. If you tune a car on a stock intake filter the gains aren't as apparent.

Yeah my bad... I forgot they are flip flopped.

It's because of less heat soak. The single mass ITB on it is why I prefer that one over the rest of the intakes. That and the price.

Well I wasn't talking about tuning or calibration, I was just talking about replacing the stock intake with an aftermarket option only... I'm not saying it's impossible I'm just saying don't expect miracles by just swapping intakes...

Bmw also designed their own Perf Intake which would indicate that there are better ones than just stock.
