okay im getting really ****ing frustrated with this air filter cover. I am trying to replace it but the cover will NOT open on the left side. the snaps do open but the cover will not. ive unscrewed that little screw. ive tried watching the only 2 videos on youtube about it but neither were helpful. I don't know how the **** it opens and im getting annoyed lol sorry. I know you are supposed to push down somewhere but ive tried that as well. down, sideways upside down everything. please help. detailed explanation and a video would be awesome if you have!
