Default Aging Coilpacks

So this morning I was driving some backroads, and going into boost around 3000rpm I lost a lot of power with a CEL. Cyl #3 misfired. After switching it out with the coil from #1 and the problem following to that cyl I determined it was the coilpack...replaced it with a new one and it's running like a champ.

I'm just wondering if since I have 98K on the car I can expect the other coilpacks to have numbered days? For example if 1 spark plug looks bad I'd replace all 4...not just the faulty one.

Also, for reference here is the OEM coil part number for EJ255/257.....I had trouble finding it and saw no mention of it on forums.

Yes, it would definitely be a good idea to consider replacing the other 3. They don't last forever.

Thanks. I picked the coil up from the dealer for 109 which is a little steep. The best I can find them for is 80 dollars, that means another $240 to replace the remaining 3. At that price I think I will hold off for a little while, but definitely get the other 3 replaced before I put on my 18g.

Also...I noticed there is some oil inside the plug hole only on the cyl that had the failed coil. I suspect this means I need a new valve cover gasket set as well? :/ I guess I'll have that done when I get my 105k tune up. Oh the joys of aging vehicles.
