2003 Sienna spark plugs change interval?

Aug 31, 2007 1 Replies

Hi:



Maintenance schedule says 96k kms (60k miles) - replace iridium spark plugs. Mine is almost at 95k kms.



How long are they good for on an average? Should I stick to the maintenance schedule or let it go for another 5k-10k kms?



Thanks in advance,



AJ.


They should be good longer, but it's easy enough to pull em out and take a look at em. While you're at it, though, why not just replace them? They're a relatively inexpensive maintenance item.
