I installed this on my 03 Yamaha Warrior. You completly remove the airbox lid and install this on top of the airbox. I could've used a 3rd hand during the install, but I had it installed within 20 minutes.
Yea this is great when you dont want to spend a lot on a air box. my led was cracked so I went to this, The velcrow was the only thing that gave me problems. It gave me a problem behind the air box an the coolant res on my banshee but i cut my old lid an just screewed it down with it.
