I have 2 questions: First, at the begining, they mentioned about front bumper removal, but none of the installation procedures mentioned this. Second, at the end, they mentioned clean and replace the filter periordically, I thought the filter suppose to last for a long time and only require wash with water and dry afterward for a dry (not oiled) filter type. My I right? Thanks for posting this.
