First Spark Plug Replacement

Which I suppose is why the literature plug change intervals are listed as 30,000 miles:

Maintenance every 30,000 miles/48,000 km
Replace spark plugs
Air filter: Replace filter element
Change engine oil and oil filter

The service intervals apply under normal driving conditions. However, we strongly recommend that you check the air filter every 15,000 miles/24,000 km and if necessary, have it replaced. (Fuel filter replacement is recommended every 60,000 miles/96,000 km).

And we get cars in the shop regularly that are more than 10 years old, and with less than 20K miles on them..........

Hello JFP,

My car is an '07 and just reached 50K, I did replaced the plugs about 15K ago, and yes, I did use a very light anti-seize coat :-)

I learned to use anti-seize compound long time ago after seeing damage on the aluminum heads... and so far I have never had an issue with it, however the copper anti-seize sounds fancy and I will have to get one of those too.. :-)

Either your "literature" is out of date, or your mis-quoting it. For example, the spark plug interval on my 987S also states "or every 6 years". For the 993 Turbo it is every 3 years, no mention of mileage. If owners change plugs when they are suppose to (time sensitive), anti seize is not necessary, and why it is not Porsche recommended.
