Do BMW do MPPSK air intake?
Exhaust end is noisy. That's what you're 90% paying for.
They could make a free flow quiet but it'd be heavier too.
If the air intake costs pumping losses (which it doesn't because of the ram air system all cars since the late 90s used to reduce valuable intake losses), it's literally 'CO2s' on the table.
Ok at very high intake requirements it's going to become limited.
So if there is a case for it then great.
But I'd want to see intake pressures as standard at pre filter, post filter, and turbo intake, at various rpm and road speeds.
Then afterwards, showing a clear benefit which would allow you to conclude it was better.
But even then it may be irrelevant until say 450bhp+
I'm all for modding. But you need proof.
If you're happy without it then again that's fine but there is every chance you're just flushing money down the air intake ;-)
