If you when available raid the grenadier parts bin and order the piece that fits under the cyclone down to the next piece of RAI you should be able to fit a normal Donaldson bowl type on to the circular pipe that the TopSpin fits to check Donaldson'sThe cyclone is an optional extra and fits onto the existing raised air intake.
Says it is for offroad use only but maybe that is because it is so damned ugly
My vehicle as configured with RAI and then if I had optioned the cyclone for another $630
