Spark plug tubes

[kk2002s]

A bit of a revised thread
Getting ready to order new plug tubes. Question to those who did this, do you do all 6 as a matter of course when only 1 or 2 actually leak?
I have 2 with minimal leaking, both driver's side, but I am of the mind set that I should just bite the bullet and do all 6

Also I'm ordering from Pelican:
Porsche originals, which need rubber seals separately
Or non-Porsche which include rubber seals

Opinions welcome
