Filter
The main reason I did the air filter way back in 94 was after removing the tank on the 1st 916 I ever worked on I found the air box lined with grit etc which had got right past the original air tube filter then of course the next step is straight into the motor, after considering every which way to go and with the knowledge that surface area for any type of filter is the most important thing to avoid suffocating the engine the JHP filter was borne. One advantage with that type is that it does not impeed the volume of the air box (just think of how much water is displaced when you put a sponge in a bucket of water) is also has little to no effect on pressurising the air box, in fact as the air tubes are not resticted it is better than the original.
As for Chris B's comments I can't stop laughing which is always a good way to start the day !
