Just changed mine. Here's the tips and tricks I used. Info only.
1) Remove plastic cover (4x 6mm quick connects)
2) Remove heat shield on drivers side (1 screw)
3) Remove shield on drivers side covering spark plug coils (pulls off - 2 points on contact)
4) Remove all the connectors to the coils (4 per side) I used a sunglass repair screw driver to lift the tab and a paint can key to slide the connectors off (for the ones I couldn't do by hand - which were 5 of 8)
5) remove 1 bolt per coil and lift coil out (4 per side)
6) Last coil by firewall is tricky to remove (I turned it about 180 and was able to clear the HVAC line (yes, it rubbed))
7) I had to use two extenders to get to the spark plugs to remove and install them (for clearance/accessibility)
8) Remove plugs - hand tighten new plugs and then torque down to spec
9) Put on coils over plugs
10) Connect connectors
11) Tighten coil to spec (1 bolt - 4 per side)
12) Replace shield on driver's side
13) Driver's side is done
14) Passenger's side
15) Remover shield (pulls off - two points of contact)
16) Undo clips for coolant hoses (2 clamps)
17) Remove all the connectors to the coils (4 per side) I used a sunglass repair screw driver to lift the tab and a paint can key to slide the connectors off (for the ones I couldn't do by hand - which were 5 of 8). The one by the firewall I turned to the left a little to help the connector slide off after the next step.
18) remove 1 bolt per coil and lift coil out (4 per side)
19) To remove coils I had to manipulate the coolant lines a little.
20) I had to use two extenders to get to the spark plugs to remove and install them (for clearance/accessibility)
21) Remove plugs - hand tighten new plugs and then torque down to spec
22) Put on coils over plugs
23) Connect connectors - the coil will have to be turned a little to get the one near the firewall back on (In my case)
24) Tighten coil to spec (1 bolt - 4 per side)
25) Replace shield on driver's side
26) Place and secure engine cover on (4 quick connects)
Estimated time 1-4 hours.
This is for info only - consult the manuals for specific instructions. Good luck!
Just wanted to say thanks for instructions as this post was spot on, but in full disclosure the space you have to work is extremely limited, its real tough to get your hands, fingers and tools in the spaces in front of the coils. I had two tools that would fit the star hex nut holding the coil on - I dropped both while working on the first coil and neither fell to the floor, I'm still looking for them. Point is have plenty of time and patience before attempting and small hands are a plus. Good luck.
