Just to add my $0.02...
Be sure to place the cover(s) on a soft surface or lay down a microfiber cloth on the surface you are working with. Upon your frustration of removing (or reinstalling) the 85th clip, you dont want to scratch your brand new (or OEM) engine cover.
Use the pick tool or small flathead screwdriver to life up prongs on clips. Before reinstalling the clips, right side up or upside down, crush down the prongs *just enough* withe pliers or a Vise grip so the clip will sit tight on the peg. Yes. Some of the pegs will be shorter and you might have to turn the clips upside down. I think there were a few pegs that i was only able to get a majority, but not all, of the textile fabric to lay before reinstalling clips. I trimmed the fabric on those as I want to say it was outer upper pegs that were shorter.
For the rubber grommet engine mounts, I didnt think of heating them up like rkberta did. Having worked on my exhaust rubber grommets, i just sprayed some diluted soap water on the grommet and the rubber grommet will just sliiiiide out of the mount and slide into the CF engine cover.
Another precaution is you will have to relocate the metal grille part of the OEM engine cover. While working with the CF cover, just be careful not to let the CF surfaces be scratched up by the metal grille.
And lastly, the CF engine cover is much lighter and more pliable, for a lack of a better word for flimsy, lol. You cant just rough and tumble remove the engine cover any more. I dont know how strong the CF rubber grommer mounts are on the CF engine cover and did not want to find out the hard way. So when removing CF engine cover, i slide my index fingers and thumbs up under the front part of the cover to try to get as close to front grommets as possible and lift the front engine mounts off the grommet first. Be careful doing this as the engine cover will pop up and hit the boot lid. In the beginning, i placed a towel on top of the engine cover so if it did hit, no damage or scratches. Now, i know how much force to use to unseat the grommets without hitting boot lid.
Then, with front grommets disengaged, i reach as far back as possible under the cover to get to rear grommets to unseat those carefully.
Whenever I take my car in for service, I ALWAYS remove the engine cover as I dont know if they will have to remove the engine cover and as much as I love and trust my Service Manager and Tech, I dont want to jeopardize my beautiful engine cover.
Btw, be careful to tactically seat your grommets on the engine mounts when putting on your engine cover back on. The metal grille will contact your beautiful and unscratched biletted oil filler cap if not careful. In the beginning, I removed my oil filler cap before placing the engine cover back on. Now, I know how to place he engine cover back on without scratching the oil filler cap. (Or maybe i know if it did scratch the cap, it will scratch it in the same place as the first time! Lol
. Oh well.....
Hope this helps....
