My mechanic suggested that at 90,000 miles I have him perform a tune-up on my 98 Boxster which currently has 87,000 miles. He recommends changing all of the plugs, plug tubes, and coils along with some filters (the filters I have done myself in the past and will do again so he doesn't need to do those)

My question is about the coils. Since the car runs great and there are no codes how "smart/wise/proactive" should I be in replacing the currently working coils too?

I understand that the coils need to come off to get to the tubes and plugs but the coils seem fine so I'm looking for some advice.
