...any ideas on exactly what needs to be replaced by now for 100k miles of driving?

Sorry, I am new here, and I am sure this has already been touched on but the sticky's didn't seem to address it and doing a search gave me little info.

I am going to replace the spark plugs with irridium tips but what else should I do???

Thanks in advance.

Skyone out.

 

why dont' u check out your onwers manual, or if you have an invoice froma past service, it should show you what needs to be replaced.

hell just go to a dealship and ask for a maintainece sheet they use

 

Ditto.

But it wouldn't necessarily be in the Owner's Manual... it should be in a Maintenance Guide that came with it. If you don't have that... go to the dealer. Or check your dealer's website. Some post maintenance schedules.

My local dealer... they don't list 100k, but a few others.

 

Spark plugs, oil, transmission fluid, air and cabin filters, coolant.

 

Are you sure about that? I could've sworn the maintenance schedule shows 120k miles for plugs.
