To "anti-seize" or not, is the question.
I don't have a Porsche factory service manual for any of my cars. I used to have the old factory microfiches for my 928.
Recently while replacing a rear wheel bearing on a 986, my techs found a steel caliper bolt seized in the carrier. Threads came out with the bolt. Machine shop on premises, so a Heli-Coil was installed. Made me wonder if Porsche uses and recommends aluminum or bronze anti-seize on steel parts directly inserted into alloy threads? I've only seen factory thread locker used on Porsche steel fasteners. What's the FSM say? Sparkplugs as well? Just oil drops or anti-seize before any torquing? For reference, I learned on Italian and British cars, and anti-seize was liberally used, especially in racing.
