So I pulled the intake to change the coil and plugs out. I re-used the gasket since its metal. I'm still getting a misfire in #8 and #2 and now I see water coming from the Secondary air pump in the picture. I ran the engine for only a few minutes and water was spilling out the bottom of it.
8&2 simultaneously indicates a bad ignition coil. Swap them left to right and see if the codes move. Which hose is the water coming out of? sketch on the photo with a highlighter.

Both 8 and 2 are getting a spark at the plugs. So I don't think the coil is the problem.

As someone else said, there is a difference between getting spark and getting spark consistently under load. The coils rarely fail completely where you get a dead miss on a cylinder ie it is running on 6 or 7 cylinders, but it does happen. What typically happens is the coil insulation starts breaking down internally and you start to get intermittent misfires at high load low rpm where the spark resistance is the greatest. The ECU can detect this long before it progresses to a dead coil/dead cylinder situation.
You should swap the coils left and right and see if the codes move, it is easy to do and cost nothing and definitively answer the question about the coils or not.
That SAI device is a vacuum valve, the only way there would be water there and it is HIGHLY unlikely is if there was coolant in the exhaust. If there was your tailpipe would be pouring coolant, you would have dead 02's on that side, and you would definitely have a blown HG on that side. Even if all that was true, I cannot imagine how there woudl be water there as it is uphill from everything and the water would have to be pumped or blown to that location.
I will swap the coil packs to see if it changes anything.
Also, I haven't seen any water coming from that spot the last time I ran it. May have just been condensation from the very moist atmosphere we have had the past few weeks.
Water/Coolant in Secondary Air.. How?
