Using hand tools the install went smooth and took about five hours from beginning to finish, but this included cutting and affixing the new grille, and there were a couple of unexpected hindrances along the way which slowed things down a bit. You are correct about having to remove the entire front bumper cover, however I am not convinced that this is 100% necessary after going through the process of removal and re-installation(at least not for my project).
I followed
these instructions for removal. Step 6 is where I ran into problems on the passenger side as the black plastic piece which holds the bumper cover snapped to/aligned to the fender would not release. This part has three small screws which had to be loosened and one of them could only be accessed with a closed-end wrench. Also, the instructions fail to mention the two 10mm bolts just inside each of the headlight housings... but those were obvious.
My project required quiet a bit of custom cutting of the very stubborn stainless steel woven mesh grille material during fitment trials so leaving the OEM grille attached to the bumper during installation was not a feasible option. I removed the bumper cover/grille combo then separated the two pieces and focused all efforts on the grille only. Once the grille was ready to be re-installed I snapped it back into place, added bolts where the two OEM rivets had to be removed, then re-installed the bumper cover/grille combo following the removal steps in reverse.
Having air tools would've sped things up quite a bit.
Regardless, I achieved the look of a RaceMeshGrille
here... but mine was only $100.00.
