Is there a 40000 mile service on 997's and how much does in normally cost @ dealer?

 

40,000 is like a 20,000. Replace oil, filters, fluids (brake) and then inspect a bunch of things. The next biggy is the 60,000 which finally calls for new plugs.

Based upon the materials going into the 40,000 job figure materials at about $400 and then some labor so figure at least $600.

 

And car sales are still slow across the board, so add 50% to that number as 'revenue enhancement.'

 

At 38K miles (close enough) & 4 years, I also had the spark plugs, air filter element, coolant, transmission oil, accessory belt & cabin filter changed out. All up, at an independent shop, about $1500. Cheap insurance & confidence that all is well. At 40K, based on my experience with the car, I would also have the battery replaced.

 

I thought modern cars (sparkplugs) last 100k miles.

Unless there is something really "special" about Porsche spark plugs, I cannot imagine this is anything above marketing and just plain overkill.

One mans $.02, take it for what its worth (probably nothing these days with recession).

 

My manual calls for plug change at 40K miles. Just had it quoted at the two local dealerships. One was $850 less 15% for PCA member. The other was $1150 less 10% for PCA member.

 

i thought the maunal say 40K or 4 years. I had the plugs changed about 3 months ago: the invoice says $438.76. had some other work done at the same time. this is in Austin.

 

The manual actually calls for plugs at 60,000 miles or 4 years of service. I am electing to do mine at 60,000 miles--per the book.

 

You are partially correct, it states "every 60,000 mls, but no later than every 4 years" for Replace Spark Plugs.

I would lean towards your thoughts that 4 years on a lower mileage car is excessive for a plug change.
