Not that I know of.
Why would they need to be?

@TXFred I played that little swap game 500 times (refer to the link I posted).
The misfire has no pattern.

If you change your plugs and are still having the issue, you can try swapping the coil on #6 with the one on #1 and see if the misfire moves to #1.

I have new plugs in it. NGK Platinums or something. The car has 71.5k miles on it now. I believe I put the plugs in at 69k.
