When should the spark plugs be changed?

[mattau]

I have a 2006 997 S. It has just under 34,000 miles. It is almost 4 yrs old.

Porsche's maintenance schedule says spark plugs should be replaced every 60,000 miles or every 4 years.

My dealer says I do not need to replace the spark plugs because I have not reached 60,000 miles.

So when should I replace my spark plugs?

I guess it's up to you. Are you going to get (or do you have) an extended warrnty? If your dealer says 60,000 you should be good if you choose to wait that long. I would do it at 40k if it was me.

Mattau, wait until 60k. If you are having ignition issues then I would look at the coil packs then pull a plug to inspect it if necessary. I have a 98 986 that has 90k miles on it and they were serviced at 60k and I just did them at 90k and except for a small split in one of the tubes that attaches to the coil all were found to be in good condition. Dont spend the money unless your having issues.

I would change them at the 4 year mark, like the Owner's Manual says. That's what I plan to do with my car too.

i changed after 4 years and was soooo happy as they pooled two cracked coils out and it now runs much better (i have 996 so 997 may have better coils).
