I was wondering why the manual recommends replacing the spark plugs at 60k and not 100k as for most platinum spark plugs?

Thanks!

 

timing belt/chain (wuteva it is), fuel filter, air filter, O2 sensors (not nessecary but they WILL go out soon after) oil change, maybe an engine flush. If you want your car to last a long time, just do it all now and you'll probably end up saving alot of time and money.

 

Yup, just do the spark plug change every 60K, they can last longer but I don't recommend it because I heard the car will not perform as well and may lose somewhat gas-mileage. Speaking of the 60K interval, I need to replace my fuel filter and change my oil.

 

Timing chain definitely *does not* need to be changed at 60K. Chains, in theory, are good for the life of the engine. If it was a belt then yes, 60K would be a good suggestion. Someone with 180K or so my want to consider a chain change.

 

You may find it difficult to remove spark plugs which have been in service for 100K miles. You wouldn't want to rip out the threads of that aluminum cylinder head. When you install new plugs put a tiny dab of anti-seize compound on the threads.
