And nobody asking what the boost is doing during this noise.
And can you make a video of the noise ? ( with audio of course )

I'm going to speak to the manufacturer of the filter and see what they say, i've seen really back K&N filters in the past that look like they've been sucked inside out nearly - i'm not sure if it's a hose or filter issue yet - i will get the car out today and see if it still happens as the last time i was out in it i didn't get an odd sounds but then i can't see whats going on under the bonnet.
Another thing i can do is mount my small camera under the bonnet to view what is happening on high boost
