That strip that runs all of the way around the car covers bolts on the front
and rear bumpers that hold the bumper covers on. Use a small screw driver to
remove the short section of the cover onthe right hand side (exposes the
hole that the recovery loop screws into), then from there proceed to remove
the remaining sections. On my car, this strip is black, but on some cars it
can be color matched.

The fenderwell liner and some plastic duct work also attaches to the bumper
cover. The fender liner also has a few screws that hold it to the inside of
the fender. The liner costs in the area of $25, as does the various ducting
parts.
