As seen in the photo for step 6, there are three tasks necessary to remove the coil packs so that you can access the plugs:

1: Remove a Torx screw holding the wiring harness to engine (circled). 2: Unplug 8 connectors on passenger side of wiring harness (below arrows). 3: CAREFULLY unplug each coil pack (arrows).

A note on spark plug gapping. The factory recommends a 0.032" gap for these plugs. You may also find other sources that state 0.028" is the correct gap (esp. If you have a tuned ECU).

These plug are pre-gapped to 0.032" from NGK. I have a stage I APR ECU tune so I split the difference and set 0.030" as my gap. Always verify gap before installing; don't just install out of the box.

After each plug is torqued correctly, reinstall everything in reverse order. Insert coil packs, plug in each CP connector securely. Tighten single Torx screw. Plug in all 8 smaller connectors.

Visually inspect everything you did, and once you are satisfied, gently push engine cover back into place. Recheck torques at 3,000 miles, replace plugs every 30,000 miles.
