Spark plug replacement
#16
seriously someone make a video of them removing the heat shield without taking off the mufflers.
When I changed my spark plugs I removed EVERYTHING. Bumper, bumper bar (aluminum), mufflers.
If I hadn't I have no idea how i'd have enough space to fit any tools in there.
Please those of you who do this without removing mufflers, please show me a video.

You can do it with the mufflers installed. In fact, the 997 Workshop Manual doesn't call for the removal of the mufflers, only the rear wheels. I suggest you do it with the mufflers installed and get yourself a really good set of universal adapters and extensions. If you need the extra space to get the plugs out then it is acceptable to remove the muffler. A good mechanic can do it with the mufflers installed.

Bumper removal will make it easier to manipulate and get the muffler with exhaust tips on off and out of the car , especially for the the first time you do it, as well as give you more room to work with. But you can wiggle the mufflers out with the bumper on and have plenty of room to work. And as Bruce said , it is satisfying. The diy above is an excellent reference

After having cursed the whole afternoon with my head below my 997.1 C4S, I understand why the practice is a bit more challenging that the theory or the books...You must have the PERFECT tools otherwise it will be a disaster... Taking off the heat shield was easy, in retrospect, compared to taking out the Beru plugs, as they are longer than the space available between the plugs cover and the muffler...especially the ones closer to the bumper, and you need to work your way from front to back... then for the plugs themselves, you need to have the perfect extension length, otherwise there won't be enough space to work...And for the torque, well, hand feeling of what 60Nm is...But yes, eventually it can be done...Is it worth it? 6 plugs cost me 37.50$, and my shop (not Porsche) wanted 620$... ( I guess this meant that they would remove the muffler and bumper, unlike me...) ...so depending on how you value your time, it can be worth an (rainy) afternoon...maybe... Not counting the mood swings and half cut fingers of course...

I've done the plugs on my .1 twice, and each time I removed the heat shields but not the bumper or mufflers. But I do remove the headers. I use some really small socket sets. I got one set from a bike repair kit, meant to fit into a saddle pack.
