If you are gonna do this yourself Mark, in keeping with your new philosophy of not getting upset or excited :
Remove both valve covers !
Just a matter of a few screws, and the gasket is rubber so you won't need to replace it.
Leave the coil packs in place, just remove the plug wires and electrical plugs.
You will be amazed at how easy it is to get to all the plugs without losing several layers of skin.
Replace the plugs, put the coil wires back on the plugs, then put the covers back on and connect the packs.
( 'A' is the front plug of each cylinder, IE top coil plug to front spark plug )
