Spark Plug and Coil Change Question
I just bought plugs and coils for my 2008 Cayenne 6 cylinder from SunCoast. I was looking for DIY instructions on how to change them. I found the one below on line that does not require removing the large top engine cover/cowling only the small front cowling that is easy to remove. The plugs and coils seem to be hard to get to without removing the large one covering most of the plug/coil area. Is this the proper procedure? IF NOT HOW DO YOU REMOVE THE LARGE TOP ENGINE COVER? I do not see any bolts or fasteners that enable its removal. Thanks, BillTMI

If not, you should. Not only will it save you some $$$, you get a great sense of accomplishment from a job well done. Even if you're not handy with a wrench or don't have a ton of tools there are some simple, routine maintenance items you can do in your Porsche without going to school to be a Porsche tech. What type of DIY maintenance projects have you tackled on your Porsche?
One such project we decided to tackle is changing the plugs in our Porsche Cayenne. While changing the plugs in our 993 can be a bit of a challenge (think dropping the motor), doing so in a 2009 Cayenne V6 is a breeze. This was our first plug change on the Cayenne and it took less than 60 minutes. On a scale of 1 to 10, with 10 being the hardest, I would put this at a 2. The only reason it's that high, is that it can be a chore to remove the coils, but this only takes patience and a bit of leverage. Here's a brief tutorial for any of you that might want to do so yourself.
Parts and Tools Needed
- 1 Socket wrench and at least a 9" extension (we connected up a 3" and a 6" to reach the deep plugs)
- 1 5/8" spark plug socket (make sure it has the little rubber grabber installed)
- 1 Porsche mystery tool found in your Cayenne tool kit
- 1 longish flat head screwdriver or some other implement to remove coils (more on this later)
- 1 Flashlight or shop light (optional)
Parts Required
No two plugs per cylinder here. Just purchase six pre-gapped plugs from your favorite Porsche parts house and you're good to go. We purchased our set six of genuine Porsche plugs for $72.00 from Suncoast.
The Process for Changing Spark Plugs in your Porsche Cayenne
Depending on your garage, experience, equipment, etc. you may want to amend these instructions slightly to fit your specific needs. Bottom line, it's a fairly easy project and you simply need to be sure not to damage the plug wire clips as they are a bit fragile. Unfortunately, we learned this the hard way. The good news is a local dealer had a replacement piece in stock and it was only $18 bucks. We'll give more detail on this at the end of the post.
1. Open the hood.
2. Remove the front plastic engine cowling. This is the small plastic strip that runs horizontally across the motor and encompasses the oil cover cap. It simply un-clips with some light tugs on each side. You'll need to remove your oil filler cap to get it completely off.
3. Once removed, you can see each of the plugs are placed squarely in the center of the manifold with the plug wire clipped to the top of the coil (remember the coils sit over the spark plugs in this engine design) via a black plastic snap on clip.
4. To remove the plug wire you'll need the mystery tool we referenced in our tool list above. If for some reason you can't find yours, you could easily fashion something out of a small piece of thick gauged wire or even a wire hanger (these can come in handy for other uses too).
5. Simply maneuver the tool so it's under the clip (as in the picture above) and give a slight tug upward. This will disconnect the plug wire cap from the top of the coil and expose the coil. If you find any debris, like the leaf we found, be sure to remove it before taking out the coil and plug. You don't want leaf litter or any other type of debris falling into the cylinder once that plug is out.
6. Now, remove the coil from the top of the plug. The hardest part about doing this is breaking the suction the coil has on the plug. Twists and turns help as do some good leverage with either your own strength or that of a screwdriver.
7. Once you have the coil out, you'll need to place it out of the way and remove the spark plug using your ratchet and socket. Remember, you're going to need that long extension as you get further back along the engine where the plugs are buried a bit deeper. We were going quickly, so we would just lie the coil along the manifold for easy access. If you're worried about knocking it around, you might want to lay it on your work bench or on a cart. We don't recommend putting them on the ground as you don't want to get them dirty and you wouldn't want to take a misstep and crush one underfoot. While they aren't terribly expensive, it could still make for a much longer day.
8. Once the plug is removed, clean out around the plug hole to remove any small debris and then simply insert your new spark plug into your socket and screw it back in. Remember not to over-tighten. Now replace the coil (again make sure it is clean of any debris) and push down until it "pops" back on. Re-clip your spark plug wire to the connector and repeat the whole process five more times.
We had one problem
Even though we knew the plug wire clips were fragile, one of ours still broke during the removal process. Fortunately, the clip that attaches from the plug wire to the coil is actually two separate part numbers (see the picture above).
If you look closely at the picture above (click on it for a bigger version), you can see where ours broke if you look just to the left of the VW logo. That's right, it's a VW part too. In fact, our local Porsche dealer didn't have one in stock, but thankfully Gary, the parts guy at Darling VW in Bangor Maine, did! It was a matter of seconds to re-attach it and we were good to go.
One DIY project on the Cayenne done. Next up is how to replace the cabin filter in your Cayenne.

Most of these modern molded plastic engine covers in various cars are secured with rubber nubs of some sort clicking into a metal clip holder thing.. Just pull up at a spot that seems right .. no tools required.
PS - maybe next time you could just paste a link to something that long... will make your post easier to digest and look at. Welcome to the forum.

Here is the link that contains pictures of the spark plug change procedure. I hope I posted it properly. If the above link does not work paste this web address in your browser:http://993c4s.com/advise/maintenance...ange-tutorial/
As you can see by the pictures the coils and plugs are very hard to get to using this DIY procedure. Regards, BillTMI
