This DIY was performed on a stock 2005 xB, so there may be some slight differences in the engine cover, ext. But this should give you a good walk through.
You need to have some kind of a feel for working on cars. This is maybe a 2 star on the scale of 1-10 with ten being the hardest.
Steal threaded spark plugs, going into an aluminum head is what this is. So your $2.00 spark plug, can destroy your $800.00 head if your not careful. So you need to have a good feel for how tight is tight enough. Always start threading spark plugs by hand on a cold engine. And always use a little anti-seize on the threads.
If we"re good on all that, then lets go to it.
Set your self up with what you need in advance. Remember you want the engine cold. So let your Scion sit over night or 3-5 hours. Anti-seize is available in small packets. If you bought your plugs at Auto-zone, they likely asked you to buy some. Know what the spark plug gap is for your Scion, mark it on the box of spark plugs, and be sure your feeler gauge has that size.
You need:
new fresh spark plugs
spark plug socket (most 16V use the small one)
ratchet.
long extension
10mm socket
a feeler gage/spark plug tool
anti-seize

Start by removing the engine cover.

Next step is to remove the coil pack bolts.

JUST THE BOLTS. We want to go 1 at a time, so we don't mix up the firing order.

Now carefully remove the fist coil pack and set it aside. This is starting from the left, just like we read here in America. lol With just the spark plug socket attached to the extension, carefully drop it down in the hole until its down in there on the bolt head of the metal case of spark plug.

Now attach the ratchet, keeping it centered in the hole, and break it loose. Once its loose take the ratchet back off, and spin it out the rest of the way by hand.
Now remove the old plug, and set it on the firewall, or someplace you can see it at a glance. This helps you remember if you get a phone call, or what ever during this project of where you left off. DO NOT LEAVE AN OPEN THREAD. Drop the old one back in or finish this one up.

Now doing this one at a time, you need to "Gap the plug" Slide the correct size in between the center electrode, and the side electrode. This should have a nice light drag sliding it in.

Now put the new spark plug in the socket, and add a little anti-seize to JUST THE THREADS. Wipe off excess from the seal, and electrode area if needed.

Now carefully set it down in there, and start threading it back in by hand. This should go nice and easy, no muscles needed. Once its snug by hand, tighten it up with the ratchet. Reinstall the coil pack and move over to your second one, repeating the steps for the rest.

After that, you just need to replace the coil pack bolts.

Reinstall the engine cover.

That's it! Don't forget to write down your miles and the date in your maintenance record book.
