Over the years, the Porsche crest located on the front of the car can take a beating due to the elements. Replacing the crest can significantly improve the appearance of your car.

The crest is attached to the bumper cover using two 8mm self-threading nuts that Porsche calls "speed nuts." The speed nut is a small aluminum disk with a putty-like insert that allows it to hold the emblem snug without the danger of denting or damaging the hood of the car. It is also important to replace the rubber seal that mates the crest flush with the hood.

The downside to replacing the crest is gaining access to it. The front bumper cover must be removed in order to access the speed nuts. Please see our article on Front Bumper Cover Removal for more information. Once the front bumper cover is removed, unscrew the speed nuts using a small 8mm socket and extension. When installing the new crest, place the edge of the rubber gasket around the crest. You may need to use a heat gun or hair dryer to heat the seal up and stretch it slightly.

The speed nuts are meant to be attached once, and removing and reinstalling them can damage the small studs on the crest. Use a small dental pick to fit the gasket around the crest before it's completely tightened down. Proceed slowly, and check the seal before you tighten up the nuts. It may take a bit of effort to get the seal flush with the bumper cover and also sitting on the edge of the crest.

The rear script on the Cayenne is a bit easier to replace. It is attached to the car with an adhesive backing. Use a tape measure or ruler to mark the location of the existing script before removing it from the rear hatch.

I like to use a heat gun on the rear script to soften up the adhesive. Be careful not to leave the heat gun pointed in one spot for too long as you can damage the paint. Keep it moving until you can take a bit of dental floss and cut through the adhesive backing. Once the script is removed, use some alcohol to clean off the remaining adhesive. Installing the new script is as simple as peeling the backing off the script and sticking it on the rear hatch.

Once the bumper cover is removed, look on the underside and remove the two 8mm speed (green arrows) nuts holding the crest in place.

Take a minute and clean the area directly behind the crest.

Take a minute and clean the area directly behind the crest. This provides a better surface for the seal when installing the new crest.

Shown here is the crest seal. Pull the lip (green arrow) of the seal around the crest. You may need to stretch the seal a bit to get it all the way around or use a small pick to pull it up into place. In either situation, using a heat gun or hair dryer to make the seal more pliable can help as well.

Here is the crest with the seal correctly installed around the edge.

The rear script on the Porsche Cayenne is attached to the car with an adhesive backing.

The rear script on the Porsche Cayenne is attached to the car with an adhesive backing. I like to use a heat gun to soften up the adhesive. This makes it much easier to remove. Don't leave the heat gun pointed at a single spot for too long as you can damage the paintwork on the rear hatch.

Once the adhesive has been heated up, use dental floss to cut the adhesive between the script and the rear hatch.
Figure 7

Once the adhesive has been heated up, use dental floss to cut the adhesive between the script and the rear hatch. Once the script is removed, use alcohol to clean off any remaining adhesive. Placing the new script on is as simple as peeling off the backing and pressing it on to the rear hatch.

Victor C Comments: I wish to add the Porsche Badge on rear lid/ deck of my Cayenne 955 ., How best can I install / fix the Porsche badge, location below the Rear wiper ., positioning just above the Cayenne letters. Do I need to buy the badge with the 8mm quick fasteners or use the Badge with 3m Double sided tape which I think iwill be less permanent and may come off over time. I appreciate your advice pls.

  Followup from the Pelican Staff: If it were me, I would go for the bolt on part. If you decide to use the tape, worst case is you have to re-do it in a few years.- Nick at Pelican Parts

  Followup from the Pelican Staff: We don't currently have that tech article. If we get a chance to perform the procedure, we will be sure to document it.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
