This week i received a box from Off the Road with some goodies among which the foam air filter set. Cos i plan on riding dirt and stuff.

I've swapped the filter. My stage 2 filter cover consists of two parts.
It can be mounted with or without the inner ring, so it seems.
Now i'd like to know if the way i mounted the stage 2 is a problem.

The filter is held down by the outer ring, so that is mandatory (duh)


But i can also put the second ring in as shown below (for demonstration purposes it is just laid on top):


I cant see why i should use the second ring also. With it, the air intake is reduced, or am i missing something?
