On request of a forum member, this video shows how to access the spark plugs once a piece of plastic is removed from under the tank. The plastic piece is used to hold a bunch of electrical connectors, so alternatives could be to cable tie the connectors out of the way as I have done, or replace the original plastic with another one that provides more access.
I dont show how to remove the plastic piece (mine was already removed), perhaps something for a later video.
The EWK 14mm magnetic socket shown in this video was purchased from Amazon.
