- Remove the spark plugs
Remove each one with a 5/8-inch spark plug socket, ratchet and extension (or a magnet and deep socket if you don't have a dedicated spark plug socket).
- Install the spark plugs
Set the new plug's gap between 1mm and 1.1mm, insert it into the socket carefully to avoid cross-threading, then tighten it to about 13 ft-lb.

Insert each coil into place, connect its wiring harness, tighten its 10mm bolt, then refit the engine trim panel and tighten its screws.
