"In this Special Series, I document the development, unboxing, installation, performance gains and sound clips of the E60 M5 & E63 M6 sealed carbon intakes. 

In this entry, I forgot my gimble, grabbed Luigi, told him to hold on and got to record the new induction noises across the spectrum."

The gear used. 

To record this sound clip, I used my Sony A7ii with a 24-105 FE 4.0 lens. Most importantly, it was using a shotgun mounted Sennheiser MK400 mic. There were no mics inside the engine bay.

The sound clip. 

It was recoded in the deep cold of January.

The high rpm woosh.

Cold air is denser, it makes the V10 breathe more, and the intake louder. Listening to the clip above, you'll immediately noise the loud air noises that grow louder and louder as I hit redline.

This is probably the most impactful acoustic change with the sealed intakes. To clarify, the sealed intakes will not reveal the raw induction noises like carbon plenums would. 

Still, I like the subtle changes. It removes another "Executive" layer to the M5 that progressively reveals the madness.  

It's obvious in this clip here when I compare the stock SMG3 S5 v S6 modes.

The bottom line: the stage 1 & sealed carbon intake pairing is the most cost efficient performance enhancing modification on the V10 M5 and M6.

You want more power?There's only one way to go next: exhale with V3 long tube headers.
