Changing the Spark Plugs CSRT-4

Can someone give me a quick rundown on the process for doing this? I do not want to screw something up. I am assuming that I have to take the one pipe off that goes to the turbo. What is the best way to do that? Thanks for all the help.

I don't claim this as the best method, but it is the process I used. Oh, and pardon the lack of proper technical names and terms. I'm far from a professional mechanic.

1- removed air pipe from turbo. Unscrew bottom clamp.
2- removed air pipe from intercooler. Unscrew bottom clamp.
3- unsnapped plastic cover above head-just pull slowly, straight up.
4- Use torque bit to loosen spark plug wire.
5- Pull off/up spark plug wire.
6- Loosen and remove old spark plug- scratch head at factory gap?
7- Install new plugs.
8- Put everything back together.

I started from left to right doing one at a time. The last one required me to unsnap wire from coil thing at top to be able to remove long plug.

The job was easy and took less than 1/2 an hour. Just make sure you have the right tools and take your time. Don't force anything. Ask any questions that you have and someone here will probably be able to help.

Oh, I used needle nose pliers to lift the old plug out of the hole once they were loosened. I learned that trick years ago with my first Neon. I'm guessing a magnet on a stick would work... What did everyone else use?

I use a spark plug socket.

Make sure the engine is completely cooled down, or else you'll be buying a new head.

And you'll burn your hand!

Yeah, I use a spark plug socket (the small one) to remove and tighten the plugs, but my socket won't pull up the old plugs, they just fall back into the hole. Do you have a new type of socket that holds them in place? Maybe I need a new tool!

Hand tight, then pretty much turn with a 3/4 inch drive ratchet until snug. You'll feel it bottom out. There probably is a torque spec, but I've never followed it for spark plugs in my years of wrenching.

Re: Changing the Spark Plugs CSRT-4

The NGK's say to turn until you feel resistance and then turn it 1/2 to 3/4 of a turn more.

The biggest tip here that has already been shared is this.

On an aluminum head...DON"T CHANGE THE PLUGS WHEN THE ENGINE IS WARM!!!
If you do, as the engine cools and then reheats the next time you drive it will strip out the threads in the head. I did this on my daughters old car not knowing it had aluminum heads. They had to bore each whole out and install sleeves. That cost several hundred dollars.

The aluminum contracts and expands at a different rate than the plugs will. If you tighten them down while it's hot (expanded) when it cools (contracts) it strips the threads around the plug.
