I was able to do this without a universal joint, sort of. Passenger side was fine, just took a bit of maneuvering around the hoses to undo the screw however, for the drivers side it was impossible without the joint, so I took off all the screws except for the most inaccessible one, in the back left of the airbox. I was able to pry it open just wide enough to disengage the filter and tease it out.
