im pretty sure that guy did a video before this one where he took the airbox apart in the engine bay with a hinged ratchet.. freaking nearly impossible!
-so i had to figure this out on my own. i just watched a vid on completely removing oem to install an aftermarket intake, and voila, easy as hell
- this guy is also wrong about the charcoal filter, 575hp car gasping for air is not optimal.
the car was not designed to have 4 filters.
the 2 charcoal filters are simply there on US spec M5's to satisfy strict california emissions regulations and their job is to filter fluorocarbon (and other gasses)backflow on shutdown and while setting. [bmw just shipped all us spec cars with CA standards because you can imagine the logistics nightmare of having only a few us specs meet CA requirements and making sure only they went to CA etc etc]
get that AFE dry wire mesh enforced filter and youre good to go.
