They are off of my 95 which I bought in August 2003. The service records do not indicate that they were changed, so they might be original, but the records are missing for the first 21k so I can't be sure. The car lived a very sheltered, pampered life, which is evident by the condition of the wires - not to mention the whole car.
BTW, the problem I was trying to correct turned out to be a timing belt that was installed 1 tooth off - by a Porsche dealer, I might add. <img src="/forum/images/smilies/968/dry.gif" class="smilie" alt="" />
