Coil #3 Failed - Replace All or Replace One?

replace 1, parts are cheap but your time isn't, and they don't all fail at once, never

I agree, but it seems to me that it makes actually better sense to replace all at once as it takes just a few more minutes once you are digged under the hood - then you know that you have it all sorted out and it will not fail in the least convenient time (freezing winter outside, summer vacation somewhere, desperate need to drive a relative with broken ankle to a hospital...) to spoil your situation.
