Time for new spark plugs at 4 years? 997.2
Hello Everyone, I like to know your thoughts and consensus on the sparkplug change for .2 cars.
For my 09' C2 the Intermediate Maintenance checklist indicates plugs should be changed at 40k miles or every four years. I'm approaching 18k miles and July 2013 will be four years on my car- what do you guys think : change the plugs or ?
As always, appreciate everyone's help..

For me, it was about peace of mind so that I could enjoy the machine to the maximum extent possible for me.
I'm on my first Porsche and my '09 997.2 4S was at 4 years and 9,000 miles last month. I chose to change out my plugs because of the risk, albeit small, of the plug's becoming more difficult to remove over time. Modern spark plug threads have a material bonded to them that is designed to reduce the risk of metal (plug) to metal (cylinder head) bonding (I'm sure there is a better word for this). The material doesn't last forever.
I'm sure the plugs came out just fine as they have on my other German vehicles that I maintain myself. I had the dealer do the full preventative maintenance and inspection which included brake fluid.
If you use a 200% over design assumption and you want 50% on the backside you could go to 6 years, but why? These are not inexpensive heads. Either do it now or within the next couple of years.
ENJOY your ride!

Consider getting them done at an Indy mechanic and get a pre-warranty expiration check done at the same time. They may pick up something that you can have Porsche deal with before your warranty goes out.
If nothing else new sparks will give you the comfort of knowing that your car is tip-top.

I did my 997.2 plugs after 4 years and similar mileage to the OP. The plugs were in fine shape, but I felt a resistance when removing the old plugs, and virtually no resistance when inserting the new plugs. This gave me peace of mind that I freshened up the mating surfaces between the steel plug threads and the aluminum heads.

My warranty expires at the end of the month. I will be taking the car in to the dealer for a 4 year service although I change the oil myself and have air and cabin filters that I ordered to DIY. I will be curious if the dealer wants to change the plugs, I have about 15K miles.
