Instructions for changing coils/plugs?

[P_Mac]

Hi there:

I have a 2005 CTT, with 75k miles. In the past few days, I've been getting a shuddering under moderate to hard acceleration. OBDII reading tells me there's a Cylinder 7 misfire, so I figured it would be a good idea to replace the coils and plugs. I searched the forum, but I don't see a DIY guide or instructions for that. If anyone had instructions or manuals, that would be immensely helpful.

Also, a recommendation on the best place for OEM-quality parts would be great, too.

Thanks in advance.

If you take your vehicle to the dealer they will be replacing your ignition coils under warranty most likely, they just announced a program to offer another 4 years warranty for this issue. Go to 6speedonline.com and do a search for ignition coils and this info should come up, or stop by your local dealership and discuss it with them. Best of luck!

Ach, thanks, but I just did it this past weekend. Pretty easy job - took about 3.5 hours, taking my time. Misfire gone, full power once again. Total cost, about $350 for all parts and shipping from PelicanParts.

Warranty is extended to additional 4 years or up to 100,000 miles for MY 2004 to 2006. Even if you have not received the official letter form Porsche USA, you can go to the dealers and ask for it, they must accept that and if you face problems you can contact Porsche USA. They distributed letters in October 2010 and won't do that again even if you ask. Also, they have mentioned in those letters that if you had this issue and you did repair it in other workshop not authorized dealer they will still accept some of the charges !! try calling Porsche USA and ask for it.
