Hey Guys,

I know Spark plugs should be replaced at 100K. That being said, I have an '05 with 67K on it. The plugs are 10 years old, should I replace them based on how old they are, or are they good until 100K?

Thanks in advance!

 

pull em and check their condition.. if bad replace, if good wait.

 

They're iridiums so should be good til 100+ K miles. Make sure they're torqued properly and drive on. You could clean them and leave them, but also just torque them and leave alone.

 

^agreed with both. its very simple to pull them to check. and its easy to check torque on them

 

They'll be fine as age isn't a problem, but might want to check to make certain they are in snug, just not a big fan of removing and replacing the same plugs, especially the one with gaskets.

 

they are fine to keep, I'd be worried about the belts though! Rubber dry rots as it ages and your timing belt is probably due for a change along with the serpentine belt and coolant.
