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.

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.

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!

Bump...

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.
