K&N Air Filters HELP!!
While I was trying to clean my K&N Air Filters when I discovered 1 of the torx screws in the air box was rounded...all the textures where star imprint on the top of the screw is are stripped off...so when I try and take it out, the screw driver just slides around
My question are:
1. how do I remove a stripped screw
2. how often should I clean the air filters?
