Spark Plug Question

[mffarrell]

I have a My2003 with <21K on the clock. The engine runs fine. I read some where that the spark plug maintenace interval is 60K or every 4 years. Is this true, and do I need to change my spark plugs?

Thanks!

Yes, even if you don't have the mileage change them at the years interval.

Plugs do start to deteriorate with age and additives in gas.

Don't forget to then note that in your service manual so you and others know its been done.

I think if you look at the 60K schedule you might see that spark plugs should be changed. I did mine at 70K and they needed it. If your 996 is running fine with all the required work done as scheduled...

then 60,000 miles or more is fine.

Remove the exhaust system and have the wheels off. Very easy at that point.

Check out the DIY on this web site and it is not a difficult task.

Does the 60K miles spark plug change interval apply to a 1999 C4? I have a 147K miles on mine, and have historically change them ever 30K miles, with Bosche Porsche spec plugs. Am I wasting my money? Should I change them less often? They never seem to be extremely worn.

For MY1999 it is 30,000 miles (per the Porsche service manual maintenance schedules).
