tools needed are in the picture below.

first remove the air intake box(im sure you guys dont need a picture for that)

second, remove the 2 T20 screws, careful you dont want to lose them.

third, take out the other 2 T20 screws on the other side and take out the coolant tank screw. dont drop them.

fourth, push together the harness and coilpacks then push the clip down and you'll hear a tiny click, there unlocked, then just squiggle them out.

fifth, put your index finger under the coilpack wear the harness would plug into and just apply pressure pushing it up.

sixth, just use the spark plug socket(with the rubber in it to pick up the plug) set 5/8th's with a 3/8's extension and loosen them, after all 4 are lose, take them out by hand.

seventh, keep them in order(pack 1 with cylinder 1...etc just in case it matters)

eighth, put the new plugs in by hand, turn them counter clockwise till it clicks then screw them in and torque them down to 22lbs....then plug them in and screw in those little T20 guys

ninth, take the oil dipshit out as it gives you more room, do the same thing on this side, NOTE: MIGHT NEED TO WIGGLE THE COOLANT TANK AROUND TO HIT THE LAST PLUG, OR USE TWO 12'' INTENTIONS LIKE ME lol.

tenth, coils are out, the last one under the coolant tank is whiteish? o well.

eleventh, put the new plugs in by hand, turn them counter clockwise till they click. then hand tight them then torque them down to 22lbs.

twelfth, put your mess back together and put the dipstick back and the 2 T20 screws,

lastly, do a final inspection, take tools out that were in there.

ALL DONE![cool]

Awesome write up! How did you figure out the plugs needed to be tightened to 22 ft lbs?

What brand does everyone typically go with? Any preferred due to performance?

Your car is already good to go with plugs!

In case someone has those 4 T20 screws lost or in my case, one was completely backed out ready to fall out and the passenger side bank were altogether missing.
I went to Lowes and in the hardware dept. In the bins, they carry these screws in metric size. only difference being that they are hex head and the head is just a little smaller. But they fit correctly and they only cost $1.10 for pkg of two.
They are made by Hillman ( Button Hd Cap Screw metric ) size is M5-.80 x 16

Awesome news. Thanks for sharing. I was dreading having to find replacements for mine...they are a little gnarly.

Not connected but you can also find those annoying wheel rotor dust shield screws in the same section at Lowes. Now those are usually just destroyed the first time you try to back them out..
I'll post the size later.
