Keep in mind Twin-Air offers 2 different powerflow kits for the CRF. One is just the filter and an aluminum cage. That's the one that is like $118. It's still a PITA to remove/install the filter with that one because you still have the huge hump on the filter base.

The other powerflow kit also has a filter and a nice aluminum cage, but it includes a new filter base that replaces the stock one in the airbox. It is flat instead of humped and allows much more room to work in there and remove/install the filter. It costs like $229. Very pricey, but I've reused mine on my 05, 06, and now I'm putting it on an 07 450F.
