Brief Description: Air Box 7 - Drill the fiberglass
Next comes drilling through the fiberglass part to the metal frame. I put the filter in and marked the fiberglass. Next, I lowered the frame 1/16 of an inch and drilled for a few rivets. Since I want to make sure the filter is tight and doesn’t allow air under it or over it, I moved it down a bit more and drilled the rest of the holes.
