Now you can move on to cutting the plastic bumper cover.
First remove the clips and screws that hold the plastic trim cover to the lower center portion of the plastic bumper cover. The plastic cover does not get re-used.

Now you will need to cut out the plastic area behind the cover that was just removed. You can use masking tape to create a line to cut next to if desired.

The plastic will need to be cut right in the grooved area where the black plastic meets the painted portion. Cut all the way up through the finned air dam area as well. Then cut all the way across the front to remove the entire finned area.
Use a sanding disk or knife and file to clean up the rough edges. The top portion along the center does not need to be perfect, it will get covered by the new Lo-Pro bumper.
