After reading the owners manual and checked You Tube on line I finally decided to go ahead and put a K&N air filter in, removing the stock paper filter. It was a successful venture but you have to disassemble several pieces and remove them before you can access the air filter. Took about twenty minutes to complete the task, and you will need a 7mm socket, with long extension, a blade screwdriver and I believe a size 15 torque screwdriver to get to the airbox.
I highly recommend you watch ZIP's video on You Tube first, as they give you more information that what the owner's manual does. You really need to be careful about the waterlines that runs across the air cleaner to the radiator. Also the right hand lower screw holding the air panel onto the radiator is a little difficult to get too as that small water hose is in the way and you have no play to move it.
Have not seen this posted here, so thought I would share my experiences with you...have patience, take your time, don't force anything and you will be all right, not hard, just be careful.
