No misfires, no codes, no change of spark plugs. I changed the spark plugs a few weeks ago, but was willing to swap them out again if anything seemed wrong after the Seafoam. If you were thinking of changing your plugs, though, I would definitely do it after the Seafoam. That seems to be the common wisdom.
Also, I don't know what that line going into your intake boot is. Definitely was not on my car.
