When do you need to replace spark plugs?

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 have 42K miles on car, got spark plugs replaced 2 months ago together with some other work - mechanic told me they were like new. as it was part of other maintenance job it did not hurt me too much financially.

I would think it is worth doing before suggested 60K miles only if you observe actual irregularities in timing or car shows some jerkiness it did not have before. from other side of this story - any maintenance is getting done so you would have better night sleep. So, I think get `em changed should cost around $300 or so. may be less. decide for yourself.
