33-2031-2, the one suggested here. I mean it fits but it is really snug and it is super hard to get the hinges on the housing to go in. Was this your experience or did it fall into place like stock one?
I have K&N Panel Filter 33-2031-1, it did fit a little tighter than the stock filter, but it did fit. Clamping the airbox back together required a bit of force, but IMO it was not excessive. I would verify that the filter is seated in the airbox properly and then clamp it shut. It should be fine.
